+- regression introduced bt 4.0.19 is fixed in signal management.
+Interruption1() can be called from itself and raises bus error (on sparc) or
+segmentation fault;
+- sqlite is upgraded to 3.7.4;
+- OpenSSL is upgraded to 1.0.0c;
+- syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
+- characters are tested in recherche_type() to avoid names like '12+';

+* Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
+- due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
+Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
+corruption. As internal memory management have been improved, a best fit
+allocator like ptmalloc3 is not required anymore;
+- gnuplot is upgraded to 4.4.1;
+- deadlock is fixed in signal handlers: same mutex was used in standard
+subroutines (without protected sections by sigprocmask() or pthread_sigmask())
+and signal handlers. A new signal handler specific mutex is added;
+- minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
+that has to be evaluated by ->NUM;
+- rplfile build process is modify to be sure that rplfile is not modified
+after rpl build stage (to be sure that rplfile checksum is not modified after
+rpl compilation);
+- AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
+modified to remove yacc code and renamed;
