(&parse_args, &print_usage): -f, --force is a new option.
(&handle_output): CPP directives might have spaces after `#'.
(&parse_args): The first file only can be frozen.
first check that the trace cache file is up to date, and then
compare its timestamp with that of the output.
* bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
the preamble. Don't require 5.005 as Autom4te::General does it,
and better yet (use `use', not `require'!).
* lib/Autom4te/Struct.pm: Rename the last occurrences of
Class::Struct as Autom4te::Struct.
* lib/Autom4te/General.pm (File::stat): Use it.
(&mtime): New, export it.
* bin/autom4te.in: Use it.
Declare `$req' is invalid if it is outdated.
Don't declare it valid before saving it if something went wrong.
must be proposed to the users.
* bin/autom4te.in (@required_trace): Remove.
(@preselect): New.
(&parse_args, &print_usage): -p, --preselect is a new option.
(&up_to_date_p): Adjust.
* bin/autoconf.in: Preselect some Autoconf macros.
(m4_divert_pop): Dump the whole diversion stack when a diversion
mismatch happens.
* bin/autom4te.in (&handle_output): Remember of the first
occurrence of a possibly undefined macro, not the last.
Complain about the possibly undefined macros in the same order as
the appear in the output.
* lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
* tests/tools.at (autoconf: forbidden tokens, basic)
(autoconf: forbidden tokens, exceptions): No longer sort
autoconf's stderr, as it is now deterministic.
Check that `dnl' is caught.
* autoconf.in ($task, task trace): Remove, merely pass --trace to
autom4te.
* autoheader.in: Don't pass `-' to autoconf, rather, a tmp file.
(Because I found no way for autom4te to accept `-').
* autom4te.in (&Request::request): Beware of M4 builtins.
(END): Don't try to remove the content of an empty dir.
(&parse_args): Default is `$f:$l:$n:$%', not `$f:$l:$n:$*'.
(&handle_output): Set a default value to `$forbidden'.
* autoupdate.in (&verbose, &xsystem): New, from autom4te.in.
($autoconf): Pass --debug and --verbose.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Clean up autom4te's
cache.
Adjust all the routines to use it.
($log): New file (autoscan.log).
(output): Dump detailed logs into $log, and a shortened version to
stderr.
(&scan_makefile): Refine the regexp catching tokens in the code.
* doc/autoconf.texi (autoscan Invocation): Document `autoscan.log'
and the `configure.ac' checking feature.
Reported by Michael Elizabeth Chastain.
* autoconf.in: Refuse such AWK.
* configure.in: Likewise.
* Makefile.am (acversion.m4): Do not use move-if-change this file
has dependencies.
* doc/autoconf.texi (Fortran 77 Compiler): Some typos.
functions, no longer use `&' to call functions as it disables
prototype checking, topological sort so that functions are defined
before being used, and put an Autoconf like nice comment to
describe the functions.
(output): Accept an CONFIGURE_SCAN parameters, and open CONF.
