[Bug nptl/320] New: rwlock features should not be dependent on XSI extensions

[sebastien dot decugis at ext dot bull dot net]

The following code won't compile:
------------------------------------------
#define _POSIX_C_SOURCE 200112L
#include <pthread.h>

pthread_rwlock_t rw;

int main(int argc, char * argv[])
{
   return pthread_rwlock_init(&rw, NULL);
}
-------------------------------------------

It compiles when I add:
#define _XOPEN_SOURCE 600

But this feature is part of the IEEE Std 1003.1, 2004 Edition (and not marked
with the XSI extension). I am unsure whether /include/features.h or
/nptl/sysdeps/pthread/pthread.h should be changed.

Thanks, 
Sebastien.
