namespace problem

Thanks for your bug report. egcs 1.1 has a hack where namespace std is
ignored. Unfortunately, it also ignores using declarations involving
std, instead of interpreting them as 'using ::string'. Here is a patch.

	* decl2.c (validate_nonmember_using_decl): Fix using-directives of
	std if std is ignored.
