* autoconf.texi:
(AC_SEARCH_LIBS, AC_CHECK_FILE, AC_CHECK_FILES,
AC_TRY_LINK_FUNC): Document.
(AC_CHECK_LIB): Indicate the absence of
action-if-not-found will not kill default action.
(AC_SYS_INTERPRETER): Alphabetize with rest of section,
s/ac_cv_sys_interpreter/interpval/
* acgeneral.m4:
(AC_TRY_LINK_FUNC): Fix arg transposition.
(AC_SEARCH_LIBS): Require autoconf 2.13, add other-libs arg,
default action now similar to AC_CHECK_LIB, returns
'searchval' shell var indicating which lib matched.
(AC_CHECK_FILES): Add underscore to HAVE_file define.
* acspecific.m4:
(AC_SYS_INTERPRETER): New shell var 'interpval' stores
internal var ac_cv_sys_interpreter.
* acconfig.h, acgeneral.m4, acspecific.m4, autoconf.texi: Change
all of the Fortran 77 code to use the new `F77' prefix instead of
the older `FC' prefix.
* autoreconf.sh (stamp): Add missing quote.
* mkinstalldirs: Write output which is not diagnostic to standard
output and not standard error. Suggested by Steve Robbins
<steve@nyongwa.montreal.qc.ca>.
* autoconf.texi: Document AC_CACHE_LOAD and AC_CACHE_SAVE. Explain
how AC_CACHE_SAVE can be used as a means of syncing the cache to
disk prior to doing something potentially fatal in configure.
* autoreconf.sh: Support several automake command line options,
and run aclocal and automake when needed. Also, create stamp files
just like automake's Makefiles would do for config headers.
Additional contributions from Tom Tromey <tromey@cygnus.com>.
* 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.
* autoconf.texi (Fortran 77 Compiler Characteristics): Added new
node documenting the new AC_F77_LIBRARY_LDFLAGS macro.
* acspecific.m4 (AC_F77_LIBRARY_LDFLAGS): New macro to determine
the linker flags (e.g. `-L' and `-l') for the Fortran 77 intrinsic
and run-time libraries.
* acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): New macro. Detects the
types of formal arguments to select(). Contributed by Lars Hecking
<lhecking@nmrc.ucc.ie>.
* acconfig.h (SELECT_TYPE_ARG1): Add.
(SELECT_TYPE_ARG234): Likewise.
(SELECT_TYPE_ARG5): Likewise.
* autoconf.texi (Defining Symbols): Documented third argument to
AC_DEFINE.
* autoheader.m4 (AC_DEFINE_UNQUOTED): Generate `verbatim'
assignment if third argument given.
(AC_DEFINE): Likewise.
* acgeneral.m4 (AC_DEFINE): Handle case where $# is 3.
(AC_DEFINE_UNQUOTED): Likewise.
* autoheader.sh: Echo $verbatim if not empty.
* acconfig.h (FC_NO_MINUS_C_MINUS_O): Add to complete the Fortran
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>

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>.

MIServer machines. Contributed by Graham K. Jenkins
<Graham.K.Jenkins@corpmail.telstra.com.au>.

* testsuite/Makefile.in (check): If DejaGNU is not installed,
print a warning and skip the `dejacheck' target (which will fail).

messages if `site.exp' or `site.bak' do not exist. Contributed by
Karl Heuer <kwzh@gnu.org>.
* config.guess: Treat all SPARC variant processors running BSD/OS
as just `sparc' for compatibility reasons. Contributed by Chris
Torek <torek@bsdi.com>.
* 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>.

Thu Apr 30 16:29:00 1998 Syd Polk <spolk@cygnus.com>
* acspecific.m4 (SETPGRP_VOID): The test for setpgrp needs
to have unistd.h included or the DEC compiler does not
flag the error that triggers setting the variable.
