Hi there.

I'm trying to build an unstable glib version here, and one of their
tests fails to build due to them #defining _POSIX_C_SOURCE to 0 and
then #including <pthread.h>, which produces the following error on my
8-STABLE machine:

/usr/include/pthread.h:184: error: expected declaration specifiers or '...' before 'clockid_t'
/usr/include/pthread.h:187: error: expected declaration specifiers or '...' before 'clockid_t'
/usr/include/pthread.h:203: error: expected declaration specifiers or '...' before 'clockid_t'

pthread.h gets its definition of clockid_t from time.h, but time.h only
creates the typedef if __POSIX_VISIBLE is >= 199309. Using __clockid_t
instead of clockid_t in the function prototypes works fine.

Should the prototypes be changed?

Thanks.
