System: GNU/kFreeBSD io.debian.net 5.4-1-586 #0 Mon Dec 5 19:45:10 CET 2005 i586 i386 AMD-K6(tm) 3D processor GNU/kFreeBSD
Architecture: i586
>Description:
Please could you consider adding __FreeBSD_kernel__ to the list of gcc pre-defines? This macro is
used by GNU/kFreeBSD to allow programs to determine the kernel regardless of its userland.
Currently, programs have to check things like this:
#if defined(__FreeBSD__) || defined(__FreeBSD_kernel__)
[ code specific to kernel of FreeBSD ]
#endif
When FreeBSD defines __FreeBSD_kernel__, it'll be much simpler:
#ifdef __FreeBSD_kernel__
[ code specific to kernel of FreeBSD ]
#endif
