Mainline as of 20060206 fails to bootstrap on alpha-dec-osf4.0f while
building libgomp:

from /vol/gcc/src/gcc-dist/libgomp/config/posix/lock.c:39:
/vol/gcc/obj/gcc-4.2.0-20060206/4.0f-gcc/./gcc/include/pthread.h:877: error:
field '_Pfield' declared as a function
and many more similar errors. The problem is ultimately due to the fact
that libgomp/posix/lock.c has
/* We need Unix98 extensions to get recursive locks. */
#define _XOPEN_SOURCE 500
#include "libgomp.h"
Unfortunately, the following trivial program
#include <pthread.h>
fails in the same way when compiled with gcc -pthread -D_XOPEN_SOURCE=500.
Since <pthread.h> has PTHREAD_MUTEX_RECURSIVE even without _XOPEN_SOURCE
defined, one can probably simply omit that definition on Tru64 UNIX (at
least V4.0F, but probably on V5.1B as well).
