>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
