performance enhancement for about a 5% reduction in the runtime of
the generated configure script.
* acgeneral.m4 (AC_LANG_FORTRAN77): Remove [] (i.e. the m4 quotes)
since it was confusing the testsuite. Also make `f77' the default
for FC, otherwise the testsuite fails.

the linker flags (e.g. `-L' and `-l') for the Fortran 77 intrinsic
and run-time libraries.

77 support.
Tue Sep 8 14:06:04 1998 Matthew D. Langston <langston@SLAC.Stanford.EDU>
* acgeneral.m4: Make the following macros Fortran 77 aware
(i.e. conditionalize whether to `#include "confdefs.h"', etc.):
(AC_TRY_COMPILE)
(AC_TRY_LINK)
(AC_CHECK_LIB)
* acgeneral.m4 (AC_LANG_FORTRAN77): Rename `AC_LANG_FORTRAN' to
`AC_LANG_FORTRAN77'. Change the Fortran 77 language macro from
`FORTRAN' to `FORTRAN77'.
(AC_LANG_RESTORE): Change the Fortran 77 language macro from
`FORTRAN' to `FORTRAN77'
* autoconf.texi: Updated Fortran 77 documentation, particularly
for `AC_TRY_COMPILE', `AC_TRY_LINK' and `AC_CHECK_LIB'.
Thu Sep 3 09:34:39 1998 Matthew D. Langston <langston@SLAC.Stanford.EDU>

* acspecific.m4 (AC_PROG_FC): New macro. Determine a Fortran
compiler to use.

whether to `#include "confdefs.h"').
* acgeneral.m4 (AC_VALIDATE_CACHED_SYSTEM_TUPLE): New macro. This
macro can be used to ensure that a configure script will not run
on a second system without removing the cache and re-running
configure. Contributed by Alexandre Oliva <oliva@dcc.unicamp.br>.
* acgeneral.m4 (AC_SEARCH_LIBS): New macro. Searches a series of
libraries for a given function. Contributed by Jim Blandy
<jimb@cygnus.com>.
(AC_TRY_LINK_FUNC): New macro. Again, from Jim.
* acgeneral.m4 (AC_CHECK_PROG): Fix a bug if the supplied path
contains colons. This was observed with some versions of NetBSD
`sh' and some versions of `bash'.
(AC_PATH_PROG): Likewise. Contributed by Tom Yu <tlyu@mit.edu>.
* acgeneral.m4 (AC_CHECK_FILE): New macro. Checks for the
existence of a file in the file system (native only).
Contributed by Theodore Y. Ts'o <tytso@mit.edu>.

through PATH.

set quotes correctly, to avoid a cache overflow on HP-UX 9.
Wed Sep 11 15:35:19 1997 Chris Provenzano <proven@cygnus.com>
* acgeneral.m4 : Always set SHELL and substitute SHELL.
When looking for a path for an executable allow the
user to override with an DOS path.
Tue Aug 5 23:00:05 1997 Ian Lance Taylor <ian@cygnus.com>
* acgeneral.m4 (AC_VERSION): Set to 2.12.1.
