[RPL/2] New RPL/2 ports

[BERTRAND Joel]

	Hello,

	Some news. I shall upload a new release as soon as possible. I have 
done a lot of work to port RPL/2 on systems that only have broken or 
don't have siginfo structure (OpenBSD, OS/2 and eCS and propably some 
others).

	Now, RPL/2 supports multithreading and multitasking on OpenBSD (and 
transliteration). I have only tested on OpenBSD 4.7 i386. This 
workaround uses shared memory (two segments by process to avoid 
alignment error). I'm trying to do some parallel computation with this 
new patch and it seems to run fine.

	On system where POSIX semaphore functions are broken, it is now 
possible to use SysV semaphores. A new configure option shall be 
available to force SysV semaphores instead of POSIX ones.

	I'm not sure that the same code is directly usable on OS/2 because I'm 
not sure that shmget() is available. I shall test as soon as possible.

	Please test last daily snapshot.

	Regards,

	JKB
