   * RPL/2 is known to run on :
 
-	- Linux (kernel 2.6.26 and above) on i386, amd64, ppc32, sparc32,
-		sparc64, alpha. Test distribution is Debian. Warning, you have to
-		use NPTL, not LinuxThreads due to a bug in sem_post() that is not
-		async safe.
-	- Solaris 9 and above on i386, amd64, sparc32 (only Solaris 9) and sparc64.
+	- Linux (kernel 2.6.26 and above). Test distribution is Debian.
+	- Solaris 8 and above.
 		It can be built out of the box on Solaris in a 32bits userland. For a
 		64bits executable, you have to modify some generated makefiles or
 		specify some options. See 64bits on Solaris.
-	- FreeBSD 7.x on i386. I have installed a FreeBSD 7.0, upgraded to 7.2
+	- FreeBSD 7.x. I have installed a FreeBSD 7.0, upgraded to 7.2
 		and RPL/2 ran without any trouble. RPL/2 does not run on early
 		FreeBSD 8.0 because sig_info_t struct is not filled. This bug is now
 		fixed. Someone has reported that FreeBSD 7.2 did not filled this
 		struct too...
-	- NetBSD 4.0 and above with a restriction. NetBSD's sigpending
-		is broken and it is impossible to use DETACH intrinsic. Bug report
-		has been done and this bug should be fixed in next NetBSD release.
-		Sigpending has been fixed in NetBSD 5.0 and RPL/2 runs fine.
-	- OpenBSD 4.7 and above.
+	- NetBSD 5.0 and above.
+	- OpenBSD 4.8 and above.
 	- Windows with Cygwin (>= 1.7.5).
+	- OS/2 and eComStation with EMX (>= 0.9d). You probably have to
+		recreate configure script and makefiles with autoreconf.
+	- Mac OS X.
 
   * RPL/2 should run on :
 
+	- AIX
 	- HP-UX (10.20 and above), but not tested for a long time.
-	- Linux (2.6.26 and above) on ppc64 and other hardware (arm, hppa...) or
-		with other distributions than Debian.
-	- FreeBSD 7.0 and above on other architecture than i386. Please not
-		that I cannot reproduce sig_info_t bug and I do not have more
-		information.
-	- NetBSD 4.0 and above on other architecture than sparc32 with restriction
-		due to sigpending bug.
-	- OS/2 and eComStation.
