65: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
66: - major bug is fixed in STD format (1E7 sq prints 1);
67: - major bug is fixed in READ intrinsic (socket). This bug was introduced
68: by a new feature in glibc.
69: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
70: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
71: "ALL" IMPLICIT when it runs in interactive mode;
72: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
73: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
74: to use SAVE to manipulate global variables;
75: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
76: subroutines;
77: - fix major memory access violation in evaluation subroutine. Only occurs
78: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
79: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
80: when X was a vector or a table.
1.63 bertrand 81: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

98: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 99: - Lapack is upgraded to 3.3.0;
1.58 bertrand 100: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 101: - ncurses is upgraded;
1.60 bertrand 102: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 103: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 104: segmentation fault;
105: - sqlite is upgraded to 3.7.4;
1.54 bertrand 106: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 109: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 110: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
111: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
112: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
113: corruption. As internal memory management have been improved, a best fit
114: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 115: - gnuplot is upgraded to 4.4.1;
116: - deadlock is fixed in signal handlers: same mutex was used in standard
117: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
118: and signal handlers. A new signal handler specific mutex is added;
119: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
120: that has to be evaluated by ->NUM;
1.49 bertrand 121: - rplfile build process is modify to be sure that rplfile is not modified
122: after rpl build stage (to be sure that rplfile checksum is not modified after
123: rpl compilation);
1.51 bertrand 124: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
125: modified to remove yacc code and renamed;
1.47 bertrand 126: - some workarounds have been written to not use buggy klibc SystemV IPCS.
127: ABORT now works on eComStation;
128: - sqlite is upgraded to 3.7.2;
129: - bug is fixed in software interrupts. When both process have different PID,
130: parent process was not interrupted if it is not group master process. To fix
131: this bug, SIGINJECT signal is not sent by child process but by control thread
132: in parent process;
1.46 bertrand 133: - minor bug is fixed in data injection (POKE) that does not work as expected
134: when child process is protected by NRPROC.
1.44 bertrand 135: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 136: - --enable-sysv-sems is added to configure script to use SystemV semaphores
137: functions instead of POSIX functions. This function is disabled or forced on
138: systems that does not provide correct POSIX or SysV semaphores subsystem;
139: - a dirty but not quick patch is written to workaround broken siginfo
140: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 141: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 142: (Unix PID);
1.41 bertrand 143: - some OpenBSD's hacks are added;
144: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 145: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.39 bertrand 148: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 149: or freeaddrinfo;
1.39 bertrand 150: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
151: - major bug is fixed in CHR intrinsic when obtained character is not printable;

157: postgresql libraries are statically linked in rpl executable;
158: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 159: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 160: - units is upgraded to 1.88;
161: - another major bug is fixed in the same variable creation subroutine.
162: Level 0 and 1 variables adresses were swapped when a global variable masked
163: a name of RPL/2 routine;
1.35 bertrand 164: - major bug is fixed in global variable creation subroutine. When a global
165: variable was created and when a local variable existed with the same name,
166: computed address of global variable was wrong;
167: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
168: is forced in front of all libraries.
1.34 bertrand 169: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
170: - BACKTRACE intrinsic is added;
171: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
172: when this structure is included in IFERR/THEN/END structure and when an error is
173: caught;
174: - major bug is fixed in analyse() subroutine. When evaluation() returned error
175: in a compiled program, analyse() caught this error twice and randomly aborted
176: with a segmentation error;
177: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
178: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
179: signals;
180: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
181: matrix.
1.33 bertrand 182: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
183: - minor bug is fixed in evaluation() subroutine. With this patch, same program

192: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
193: linux (false mremap() prototype);
194: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 195: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 196: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 197: - minor memory leak is fixed in OPEN intrinsic (socket);
198: - major bug is fixed in IFERR structure. Only occurs in compiled program;
199: - major bug is fixed in copie_objet() and liberation(). Only concerns
200: format in FCH (file descriptor) and SCK (socket descriptor);
201: - debug routines are improved;
202: - PROCID is added;
203: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
204: and to not use swap;
1.26 bertrand 205: - major bug is fixed in sql support. SQL connections were closed in all chield
206: process;
207: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
208: discovered in Solaris thread safe allocators (libmalloc and libumem) that
209: are first fit class allocators. Solaris libmtmalloc works better and is
210: a best fit class allocator but its performance is poor than ptmalloc3
211: performance;
1.24 bertrand 212: - major bug is fixed in ROW+ intrinsic (new row was not added where it
213: should);
214: - minor bugs are fixed in interruptions.c (semaphores values when error is
215: caught);
216: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
217: created by SPAWN;
218: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
219: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 220: - ONEXIT is renamed in ATEXIT;
221: - ONEXIT new intrinsic is added.
1.20 bertrand 222: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
223: - major bug is fixed in static and shared variables initialization subroutine.
224: This bug only occurs when RPL/2 tries to create a shared or static variable
225: from an expression;
226: - major bug is fixed in copie_etat_processus(). A field that contains
227: information about shared variable was not copied to new processus structure;
1.19 bertrand 228: - some little memory leaks are fixed in evaluation(), recherche_type() and
229: sequenceur(). They only occured when syntax error were caught;
230: - IMPLICIT causes execution error instead system error;
231: - Hurd support is improved but currently broken because Hurd does not support
232: SIG_INFO. Work in progress;
233: - OpenBSD specific support is removed from sources;
234: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 235: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

272: sends preprocessor output to standard output. This option is used by
273: rplc (RPL/2 compiler).
1.13 bertrand 274: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
275: - in formatted file, string format returned a variable length string even if
276: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 277: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 278: - keyed access files support is added. Currently, only formatted files are

327: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
328: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
329: signals sent to main process were not caught because DAEMON did not replace
330: old pid by new one;
331: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
332: evaluation when an error is reported from a subroutine in another subroutine.
333: For example, error was not caught in following program when it is executed with
334: -p option :

354: encountered at end of block, subroutine aborts with an execution error;
355: - major bug is fixed in OPEN (TCP/IPv4 sockets).
356: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
357: - DISP now locks stdout;
358: - rpliconv is added to replace standard iconv provided by operating system.
359: Indeed, conversion between different encodages requires transliteration
360: that is not offered by some iconv utility;
361: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
362: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
363: not be found), SYSEVAL enters in a dead lock;
364: - fprintf is replaced by some functions that allow transliterations between
365: locales;
366: - '"' can now be used in strings ("\"");
367: - iconv is called with -c in preprocessor stage. It is done to write
368: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
369: - double free is fixed in liberation() (type SQL, only occurs when locale is
370: set);
371: - LOCALIZATION, UCASE and LCASE are added;
372: - major bug is fixed in EXIT intrinsic that was able to return a false
373: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
374: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
375: used in onLoading from shared library, USE was pushed on stack as algebraic
376: expression;
377: - libiconv is upgraded to 1.13.1;
378: - gnuplot is upgraded to 4.2.6;
379: - gsl is upgraded to 1.13.
380: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
381: - pipe() is overwritten by a macro to avoid a system error. Communication
382: between process are done with pipes and these pipes are managed by a
383: specific asynchrone thread. If a script try to create more threads than
384: management thread can destroy, you can quickly achieve maximum number of
385: opened files and pipe() shall return a system error. This macro tries to create
386: pipes. If pipe() function returns an error, macro waits and retries. If
387: number of retries is greater than a hardcoded value, macro returns an error;
388: - major bug (deadlock) is fixed in process and thread management. I hope
389: this bug shall be the last one;
390: - major bug is fixed in DET intrinsic (determinant was computed without LU
391: diagonalization);
392: - SWAPCNTXT is added;
393: - minor bug is fixed in Makefile.am (licences rule).
394: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
395: - some bugfixes are added in process management;
396: - all process management is rewritten to avoid usage of defunct process
397: or thread number;
398: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
399: was called before a pending interruption5 (SIGFSTOP), signal handler uses
400: a freed semaphore and corrupts heap;
401: - CLRERR is added to erase previous errors;
402: - ERRN and ERRM return exception message and number;
403: - major bug is fixed in interruptions.c. All signal are now bufferised
404: when semaphore_liste_threads is null to avoid deadlock. This bug only
405: occured when STOP was sent to a dying thread or process (when this thread or
406: process was running retrait_thread());
407: - matrix rank is computed before matrix inversion;
408: - file locks are added to stdin and stdout. stderr is not locked because
409: all messages written by signal handlers are sent to stderr;
410: - configure.in script is modified to test gcc version and avoid a bug in
411: gcc older than 4.4;
412: - some benchmarks have been done :

481: - --enable-profile flag is added to configure script. When this flag is
482: enabled, rpl is built with -pg option;
483: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
484: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
485: process is killed;
486: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
487: know typeof() intrinsic function. This function is not standard but exists
488: under Sun Studio, gcc, and maybe some others compilers. If this function does
489: not exist on your compiler, you can change its definition by old one in
490: src/rpl.h;
491: - fflush() can now be interrupted by signal (SunOS);
492: - fflush(NULL) is called before all fork() occurrences;

513: deadlock when a huge amount of threads is launched);
514: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
515: arguments types are unsupported;
516: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
517: data are buffered. PLOT is used to draw these objects.);
518: - MARK instrinsic is added;
519: - new allocator mechanism is written;
520: - some regression bugs have been fixed, some memory leaks too.
521: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

531: static variable that is shared by multiple threads;
532: - '->' intrinsic is improved. All object copies have been avoided;
533: - -n flag is added to catch HUP signal. stderr and stdout are redirected
534: to a file, stdin is redirected to /dev/null when control process is killed;
535: - a mutex is added to each object (before this modification,
536: RPL/2 used a global mutex and performances in multithreaded programs were very
537: poor.);

551: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
552: that all programs that worked with old SQL intrinsic can now work with
553: SQLQUERY. With all new programs, you can open a real connection to databases;
554: - NRPROC is added. This new intrinsic is used to catch error from child
555: process. Without NRPROC, any errors returned by child process cause
556: main process to abort;
557: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
558: starts a new process). There are no mutexes in RPL/2 because all spawned process
559: use specific context. Nevertheless, shared variables and associated mutexes
560: should be added;
561: - -D flag and DAEMONIZE intrinsic have been added;

611: - ->TABLE and TABLE-> intrinsics are added;
612: - major bug is fixed in recherche_type(). Only occurs when rpl executes
613: precompiled scripts;

631: nullified lists;
632: - rplexternals.h is modified and improved;
633: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

647: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
648: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
649: workaround for this major bug. Nevertheless, all others capabilities seems to
650: work fine;
651: - '->' is modified to return error when program tries to initialiaze two

699: before starting interrupt evaluation;
700: - -f parameter is added when iconv is called;
701: - as old file program was bugged, a new option is added to configure script.
702: When configure is called with --disable-encoding-autodetection, make does not
703: try to detect source encoding. Please, do not use if RPL/2 can be built
704: without this option !
705: - new garbage collector (and more efficient) is written;
706: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
707: not support real time signals, RPL/2 cannot use multitasking functions;
708: - error returned by preprocessor are now catched by RPL/2;
709: - -p option is added. With this option, all scripts are compiled before
710: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
711: 40% faster;
712: - read and write operations in pipe() are rewritten to be sure that such
713: operations are atomic;

855: - external wrapper (rplplot) is written to force usage of gnuplot provided
856: by RPL/2 if it is built during build process. If this build does not exist,
857: it tries to launch regular gnuplot;
858: - gnuplot is added to source tree to avoid some trouble between preinstalled
859: gnuplot and release used by RPL/2. This addition to source tree is
860: required by some incompatibility between gnuplot releases;
861: - Lapack is upgraded to 3.1.1 release;
862: - GSL is upgraded to 1.9 revision;

910: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
911: versions of PROTECT and UNPROTECT that only deal with global variables
912: (see RCL/SAVE);
913: - variable management routines have been rewritten. The new ones are
914: uncompatible with the old ones. Before these changes, a local variable
915: was exported to a child subroutine, but cannot be modified into this
916: child subroutine. Now, a local variable is accessible only in its subroutine;
917: - SAVE intrinsic is added to manipulate global variables;

1238: fine...);
1239: - NOT is not correctly formatted in formateur.c:
1240: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1241: with a NOTZ function !
1242: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1245: - RPL/2 is tested with efence and valgrind;
1246: - configure.in script is modified;
1247: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1308: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1309: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1310: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1327: - SCLS is added;
1328: - DRWS now uses COLS to draw 2D graphics;
1329: - PPAR and SPAR are written. SPAR returns a list that contains the
1330: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1331: statistical variable, or "DISABLED" if its type is not one of the type of
1332: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1333: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1334: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1335: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1336: disabled. Arguments of EXTERNAL are case sensitive because the external
1337: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1338: of known external functions but add the new list to the last. { "all" }
1339: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1340: external names of the known functions;
1341: - mkrplso.in is modified.
1342: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1356: VISIT does not find a name in level 1;
1357: - configure.in script is modified to add a new test (--enable-debug
1358: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1359: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1360: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1361: 'MATRIX' { 2 2 3 } GETR;
1362: - LOGSCALE intrinsic is improved and now, it can be used as
1363: { "main" "auxiliary" X Y } LOGSCALE;
1364: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1365: same than AXES:
1366: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1367: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1368: { { -10 10 } "automatic" } SCALE.
1369: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1370: because it changes only the dimension of the screen. To have a logarithmic
1371: scale, you must use LOGSCALE intrinsic:
1372: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1373: screen on second scale;
1374: - { X X } autoscale and { Y Y } logscale are now invalid;
1375: - *D is added (depth multiplication, for 3D graphics);
1376: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1377: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1378: - a major bug is fixed in GETI instrinsic when it is used with a name
1379: that contains a matrix or a vector (bad upper bounds conditions in
1380: incrementation);
1381: - DISP intrinsic now uses the 33-th flag. When it is not set
1382: (default), a final carriage return is sent to the terminal;
1383: - AXES intrinsic only takes a list that can contains the keywork
1384: "main" or "auxiliary". Before this modification, this keyword was in
1385: the first stack level;
1386: - vim syntax file is upgraded;
1387: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1388: option;
1389: - LAST is now disabled in the main loop of INT intrinsic;
1390: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1391: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1392: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1393: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1394: in 0);
1395: - LAST is disabled in the main loop of DRAW intrinsic;
1396: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1397: evaluation of an equation, the system stack is returned corrupted to the
1398: sequencer;
1399: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1400: of a loop are not integer or real.
1401: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1403: have the same name. To improve the compilation() subroutine, I have to
1404: add some tests in gestion_variables.c;
1405: - recherche_type() subroutine ad some other connex subroutines are improved.
1406: Now, some syntax errors about object are caught and do not perform sequencer
1407: hangup;
1408: - readline is upgraded (minor compilation bug with recent gcc);
1409: - Makefile.am's and configure.in scripts are improved.
1410: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1411: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1412: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1414: - recherche_type() is rewritten to be faster;
1415: - gsl is upgraded (release 1.3);
1416: - ncurses is upgraded and patched (release 5.3);
1417: - recherche_instruction_suivante() is fixed (string research with included
1418: '"') and rewritten to be faster;

1429: - a minor bug is fixed in evaluation subroutine;
1430: - vim syntax file is improved;
1431: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1432: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1433: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1434: is a quick and dirty workaround...);
1435: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1436: - rplconvert is improved.

1518: deleted too!;
1519: - configure script is improved (and it seems to be good ;-) );

1536: signal is an asynchonous "HALT" command;
1537: - SIGINT (CTRL+C) variables stack corruption is fixed;
1538: - IFERR seems to be fixed (in equation evaluation routine);

1546: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1547: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1548: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1549:
1550: Newton:[~/rpl/rpl] > time make install
1551: ...
1552: real 338m39.623s
1553: user 324m32.290s
