Mainline as of 20060206 and the 4.1 branch as of 20060208 fail to bootstrap

This is the same problem as PR libgomp/26308: libobjc/thr-objc.c defines
_XOPEN_SOURCE=500 before including <gthr.h> and thus <pthread.h>, which
doesn't work on that platform. This is a regression from the 4.0 branch
introduced by this patch:

The comment above the definition unfortunately isn't specific about this.
I've just submitted the patch proposed in the PR as a workaround:

I can't really look into it because it's specific to an OS I don't have access
to. The proposed change looks reasonable. Reverting my change will very
likely break the build on well-behaved OSes.
I suppose it might be possible to fix the build on OSF with fixincludes, since
it looks a lot like some header bug.

Do you remember which OS needed that define? thr-objc.c seems to have
worked without for a long time.

Probably. I might investigate this.

It was GNU/Linux, for sure. Earlier gthr-posix.h used #pragma weak, which did
not require declarations for referenced symbols, whereas the new weakref
machinery requires earlier declarations to obtain the type for the weakref
declaration.
