Looks much more sane than current situation.

It can be useful to exclude blocks of lines in include files
when we install them, unrelated to libc_hidden_proto's.
Also it can be trivially expanded to remove, for example,
#warning "mjn3 FIXME: None of these prototypes have implementations."
#warning "mjn3 FIXME: a bunch of unimplemented function prototypes."
# if defined __USE_XOPEN2K && defined __UCLIBC_HAS_ADVANCED_REALTIME__
/* High-resolution sleep with the specified clock.
This function is a cancellation point and therefore not marked with
extern int clock_nanosleep (clockid_t __clock_id, int __flags,
__const struct timespec *__req,
struct timespec *__rem);
/* Return clock ID for CPU-time clock. */
extern int clock_getcpuclockid (pid_t __pid, clockid_t *__clock_id) __THROW;
#endif /* __UCLIBC_MJN3_ONLY__ */
