re PR other/26489 (compilation of c++ fails in eh_alloc.cc on NetBSD)

	PR other/26489
	* gthr-posix.h (__gthrw2): Define to take three parameters, the
	declared name, the weak reference name, and the typeof name.
	(__gthrw): Avoid expanding the declared name suffix.
	(__gthrw3): New Tru64 specific macro to simplify the OSF/1 decls.
