#ifndef SHARED in pthread.h

[Roland McGrath <roland at hack dot frob dot com>]

I just noticed in nptl/sysdeps/pthread/pthread.h:

	/* Internal interface to initiate cleanup.  */
	extern void __pthread_unwind_next (__pthread_unwind_buf_t *__buf)
	     __cleanup_fct_attribute __attribute__ ((__noreturn__))
	# ifndef SHARED
	     __attribute__ ((__weak__))
	# endif
	     ;

This is using the internal macro SHARED in a public header, which is bad.
This is inside the #else of:

	#if defined __GNUC__ && defined __EXCEPTIONS

which I think will always be true when building libc itself.

So perhaps this conditional should just go away?

But I'm not really clear on all the details here.


Thanks,
Roland
