Thanks for reporting this.  You shouldn't need that patch; all you
should need to do is to compile with -DHAVE_STRERROR=1.  That being
said, I think HAVE_STRERROR should default to 1 these days; strerror
has been in the C standard for more than a decade and I no longer have
access to any hosts that lack strerror.

Here's a proposed patch.

	* Makefile, private.h: HAVE_STRERROR now defaults to 1, since
	strerror is now ubiquitous.
