performance enhancement for about a 5% reduction in the runtime of
the generated configure script.

since it was confusing the testsuite. Also make `f77' the default

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.

AC_DEFINE.

assignment if third argument given.

77 support.

`FORTRAN' to `FORTRAN77'

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

AC_OUTPUT_MAKE_DEFS here too: Match `#define foo' without trailing

From G.Wilford@ee.surrey.ac.uk.
Also use the sed trick when not using a config header file.
Check for ${ac_tool_prefix}PROG-TO-CHECK-FOR first. If not found and third
arg given, and ${ac_tool_prefix} is nonempty, check for unadorned
PROG-TO-CHECK-FOR as well. Last choice use VALUE-IF-NOT-FOUND.
CONFIG_STATUS to allow overriding the name of config.status.
(AC_TEST_PROGRAM): Add missing newline.
Always include 'fi' for cross-compiling if.
From Jim Meyering.
Make default cache file ./config.cache,
