* acgeneral.m4 (AC_HELP_STRING): Rewrite in m4. Have m4 work, and
give a break to sh.
(_AC_FOREACH): Be careful not to evaluate the arguments. A loop
over *quoted* macro names should loop over the macro names, not
upon their expansion.
(_AC_COMMATIZE): Also swallow end of lines.
* autoconf.texi (Pretty Help Strings): Updated to reflect the
changes.
1999-09-13 Akim Demaille <akim@epita.fr>
* acgeneral.m4 (ifset): New helpy tiny macro.
(AC_OUTPUT): Improved --help of config.status.
(AC_OUTPUT): Remove inconditionaly all the files to be updated.
(AC_OUTPUT): Use pid to define the temporary file names in order
to allow parallel builds.
* autoconf.sh: Substitute also /@BKL@/[/ /@BKR@/]/ /@DLR@/$/ so
that these characters are more easily accessible from m4 without
turning changequote juggling into a nightmare.
* acgeneral.m4 (AC_WRAP): New macro, for word wrapping.
* autoconf.texi: Update the direntry for more modern Texinfos.
Add pointer to configure and config.status.
Remove the dots from the menus: horizontal space is precious.
(Invoking config.status): More traditional presentation of the options.
* acgeneral.m4 (AC_ACVERSION): Bump to 2.14.1 to differenciate the
experimental branch from the main trunk.
* acgeneral.m4 (AC_FOREACH_COMMA): New macro, to perform m4 loops
on m4 lists (i.e., list='(item_1, item_2, ..., item_n)').
(AC_FOREACH): New macro, to perform m4 loops on shell lists (i.e.,
list='item_1 item_2 ... item_n').
* acgeneral.m4 (AC_DEFUN): Now accept two other optionnal
parameters: the name of the macro which is specialized here, and
the name of the first argument. For instance `AC_CHECK_FNMATCH'
should be declared as specializing `AC_CHECK_FUNC' for `fnmatch'
as first argument.
* acgeneral.m4 (AC_CHECK_FILES): Use AC_FOREACH for looping,
instead of the shell's loop.
* acgeneral.m4 (AC_TR): In addition to transliteration, provide a
mean to specify the valid destination alphabet and a default
character for aliens characters. This is in order to remove
characters such as `+:-' etc. that may appear in file names,
but are not valid for shell variables or #defines.
(AC_TR_DEFINE): New macro, maps anything to a valid uppercase
#define rhs.
(AC_TR_UPCASE_NAME): Replaced by AC_TR_DEFINE. All callers
changed.
(AC_TR_UPCASE_FILE): Likewise.
* acgeneral.m4 (AC_TR_SH): Don't use the generic AC_TR: there is a
difficult problem of quoting between m4 and sh. Use the variable
$ac_tr_sh to work around this difficulty.
(AC_VAR_TEST_SET): New macro, which tests if a variable is set.
(AC_VAR_IF_SET): New `ifelse' macro.
(AC_CACHE_VAL): Use AC_VAR_IF_SET.
(AC_INIT_NOTICE): Define $ac_tr_sh.
* acgeneral.m4 (AC_CHECK_FILE): Converted to use AC_TR and AC_VAR
families.
* acgeneral.m4: Fixed the regular expressions: `$' shall not be
portably in a sed \(\) group.

and F77_FUNC_ CPP macros to properly mangle the names of C identifiers
so that they match the name mangling scheme used by the Fortran 77
compiler.
(AC_F77_NAME_MANGLING): New macro to test for the name mangling scheme
used by the Fortran 77 compiler.
* acspecific.m4 (AC_PROG_INSTALL): set INSTALL_SCRIPT to
${INSTALL} so that automake doesn't propogate install time flags
for INSTALL_PROGRAM into INSTALL_SCRIPT.
* acspecific.m4 (AC_EXEEXT): Do not consider `.xcoff' as a
possible executable filename extension. Contributed by Robert
S. Maier <rsm@math.arizona.edu>.

when $CXXCPP is overridden in the supervisory shell. Contributed
by Michael Schoene <mrs@mlc.de>.
* 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.

on a second system without removing the cache and re-running
configure. Contributed by Alexandre Oliva <oliva@dcc.unicamp.br>.
