/* psm: keep this before internals.h */
#if 0
vda: here is why:
headers contain libc_hidden_proto(foo).
In libpthread/linuxthreads.old/sysdeps/pthread/bits/libc-lock.h
adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
will not warn:
/* libc_hidden_proto(foo) */
weak_extern (__pthread_initialize)
/* libc_hidden_proto(foo) */
but adding after will! Which is extremely strange -
weak_extern expands into just "#pragma weak __pthread_initialize".
TODO: determine whether it is a gcc bug or what
(see gcc.gnu.org/PR36282).
For now, just include all headers before internals.h
(they are again included in internals.h - maybe remove them there later)
