[RPL/2] RPL/2 4.0.16

[BERTRAND Joel]

	Hello,

	New release of RPL/2 is available. Some news :
- minor bug is fixed in evaluation() subroutine. With this patch, same 
program returns same result with or without -p flag;
- ncurses 5.7 is upgraded to 20100619;
- openssl is upgraded to 1.0.0a;
- interrupt stacks are now FIFO instead of LIFO;
- debug memory allocation subroutines are improved to run in 
multithreaded programs;
- some memory leaks are fixed in process management (SPAWN and DETACH);
- version verification is added to shared objects;
- -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 
64 bits linux (false mremap() prototype);
- major bug is fixed in rpliconv. getc() returns an int, not a unsigned 
char.

	Regards,

	JKB
