.. and it causes other problems instead, namely the crap code generation for __.
Apparently glibc fixed it totally differently, and the kernel actually
doesn't care at all. We'd probably be best off just removing those
#defines entirely. Especially since the kernel doesn't even *use*
those things.
The kernel _does_ have these odd #define's in <linux/time.h>:
#define NFDBITS __NFDBITS
#define FD_SETSIZE __FD_SETSIZE
#define FD_SET(fd,fdsetp) __FD_SET(fd,fdsetp)
#define FD_CLR(fd,fdsetp) __FD_CLR(fd,fdsetp)
#define FD_ISSET(fd,fdsetp) __FD_ISSET(fd,fdsetp)
#define FD_ZERO(fdsetp) __FD_ZERO(fdsetp)
but apart from __NFDBITS and __FD_SETSIZE, the kernel doesn't even
seem to define those __FD_xyx macros at all (although possibly they
are hiding in some odd auto-generated headers, I didn't check). I
think this is all silly left-overs that nobody really wants any more.
glibc clearly doesn't.
