PatchSet 4823 
Date: 2004/06/04 20:28:14
Author: guilhem
Branch: HEAD
Tag: (none) 
Log:
Fixed stack size detection on some linux architectures.

        * config/m68k/linux/md.h,
        config/powerpc/linux/md.h: Implemented mdGetStackSize().

        * config/i386/linux/md.h: Cleaned up as soft limits are always
        the lower bound in the Linux kernel.
