	autoreconf would end up executing incorrect shell code (e.g.
	"test ! -f 1.h 2.h.in") in such cases.
	Patch submitted in parallel to bug-gnu-utils@prep.ai.mit.edu.
	
Fri Oct  3 18:10:39 1997  Ian Lance Taylor  <ian@cygnus.com>

	ac_max_here_lines here from AC_OUTPUT_HEADER.

	* autoheader.sh: Take the multiple-include protection back out.
	It's not needed for a file that just #defines stuff, and, as Ken
	Raeburn pointed out in Apr 1994:
	Since you don't make it optional, and you don't give the writer of
	configure.in much control over the name of the symbol, it also would
	prevent one "config.h" file in a subdirectory from including
	"../config.h" as a way to avoid duplicating some common tests.

	* acspecific.m4 (AC_PROG_CC_WORKS, AC_PROG_CXX_WORKS): Don't try
	running a program, just try linking.

	compiler works before checking whether it's a GNU compiler.
	(AC_FUNC_VFORK): Call _exit after perror.
	(AC_PATH_XTRA): Go back to using -R, as setting an env var as part
	of CC doesn't get eval'd correctly to actually work.
	Directly test whether a space is needed after -R.
	Don't add "-L" to LDFLAGS if $x_libraries is empty.
	(AC_FUNC_STRFTIME): Check for it in -lintl only if it's not in the
	normal libraries.

	* Test release 2.10.3.

	* testsuite/Makefile.in (dejacheck): New target, suggested by Tom
	Tromey <tromey@creche.cygnus.com>.

	* acspecific.m4 (AC_AIX, AC_MINIX): Remove warnings about AC_TRY_LINK.
	These macros don't change the linkage options.

	* Test release 2.10.2.
	
	* acspecific.m4 (AC_PROG_CC, AC_PROG_CXX) [GCC]: Use -O2 instead
	of -O.  Suggested by fnf@ninemoons.com (Fred Fish).
	
	* acgeneral.m4 (AC_OUTPUT_HEADER): Support passing
 	AC_CONFIG_HEADER a value containing shell variables.  Suggested by
 	Markku Savela <msa@msa.tte.vtt.fi> and Julian Onions
	<j.onions@nexor.co.uk>.

        AC_TRY_CPP): Show the test program in config.log if the test fails.
	From Karl Berry <karl@cs.umb.edu>.
	
	* testsuite/config/unix.exp: Run the configure script as "./script"
	in case the user doesn't have "." in their PATH.
	
Mon Nov 11 18:02:58 1996  David J MacKenzie  <djm@catapult.va.pubnix.com>

	* acgeneral.m4 (AC_TRY_COMPILE, AC_TRY_LINK): Deal with smart
	compilers that know that an unused function doesn't have to be
	linked in: call the function directly from main().
	(Removing a legacy from when they tried to run the code, I think-djm.)
	From fnf@ninemoons.com (Fred Fish).

	* acspecific.m4 (AC_FUNC_GETLOADAVG): Rename ac_save_LIBS to avoid
