* configure.in: Check whether getuid and getgid exist.

* archive.c: Define getuid and getgid as macros if HAVE_GETUID or
	HAVE_GETGID are not defined, respectively.
	(bfd_write_armap): Don't special case on _WIN32 for getuid and
	getgid.
	* configure.host: Set ac_cv_func_get{ug}id for *-*-windows*.
	* configure, config.in: Rebuild.
