	correctly.

	* sunrpc/clnt_simp.c: Test for gethostbyname_r function correctly.

	* sunrpc/clnt_gen.c: Test for gethostbyname_r and getprotobyname_r
	functions correctly.

	* inet/rexec.c (rexec): Test for gethostbyname_r result correctly.

	* inet/rcmd.c: Test for gethostbyname_r result correctly.  Optimize
	file reading a bit.

	* sysdeps/generic/glob.c: Test for getpwnam_r result correctly.

1999-06-28  Andreas Jaeger  <aj@arthur.rhein-neckar.de>
