Subject:	tiny winsup config patch
Message-ID:	<Pine.SUN.3.93.990215155240.22969G-100000@modi.xraylith.wisc.edu>
MIME-Version:	1.0

The following is a trivial patch to winsup configuration that handles a
few glitches currently in the snapshots. Note that I've not included patch
to regenerated configure.

Against 1999-02-08 snapshot.

Sun Feb 14 17:22:09 1999  Mumit Khan  <khan AT xraylith DOT wisc DOT edu>

	* configure.in (EXE_LDFLAGS): Always add newlib if part of the
	build tree.

	* utils/Makefile.in (INCLUDES): Add newlib include directories.
	(LDFLAGS): Replace this with
	(ALL_LDFLAGS): this to avoid being overridden from higher level 
	Makefiles.
