error_constants.h (posix_errno): Guard not_supported use of ENOTSUP.

2008-02-14  Benjamin Kosnik  <bkoz@redhat.com>

	* config/os/generic/error_constants.h (posix_errno): Guard
	not_supported use of ENOTSUP.
	* acinclude.m4 (GLIBCXX_CHECK_SYSTEM_ERROR): Add check for ENOTSUP
	for OpenBSD.
	* aclocal.m4: Regenerate.
	* configure: Rengerate.
	* config.h.in: Same.
