	patching, remove it.
	(get_some_switches): Recognize -E option.

	that doesn't change the exit status.

	* Makefile.SH: Change clean, distclean, and realclean targets a
	little so they agree with the GNU coding standards.

	* Configure: Recognize Domain/OS C library in /lib/libc.

	* pch.c: Fixes from Wayne Davison:
	Patch now accepts no-context context diffs that are
	specified with an assumed one line hunk (e.g.  "*** 10 ****").
	Fixed a bug in both context and unified diff processing that would
	put a zero-context hunk in the wrong place (one line too soon).
	Fixed a minor problem with p_max in unified diffs where it would
	set p_max to hunkmax unnecessarily (the only adverse effect was to
	not supply empty lines at eof by assuming they were truncated).

	declaration and tests to determine its return value type.  It
	conflicts with ANSI C systems' prototypes in stdio.h and the
	return value of sprintf is never used anyway -- it's always cast
	to void.

	on the command line).  From Paul Eggert.

	* pch.c (another_hunk): Fix from Wayne Davison to recognize
	single-line hunks in unified diffs (with a single line number
	instead of a range).

	* inp.c (rev_in_string): Don't use `s' before defining it.  From
	Wayne Davison.

	* Apply unidiff patches from davison@dri.com (Wayne Davison).

Wed Mar  7 23:47:25 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
