name, so that symlinks to 'autoconf' work properly. Bug reported
by Bruno Haible.
* bin/autoheader.in (AUTOM4TE): Likewise.
* bin/autoreconf.in (autoconf, autoheader): Likewise.
* bin/autoscan.in (autom4te): Likewise.
* bin/autoupdate.in (autom4te): Likewise.
Remove $filepath, useless.
(&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
variables, they are really part of the tokens.
Split the input line on spaces and then look for tokens.
Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
because of `lex$U.$(OBJEXT)'.
(&scan_files): Use "@list" instead of join.
* doc/Makefile.am (CLEANFILES): Add *.fns.
directives.
(&scan_sh_file): Remove a duplicate pattern.
(&check_configure_ac): Use long options.
* lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
* bin/autoupdate.in: Ditto.
* bin/autoheader.in: Reworded a few comments.
* bin/autoconf.in: Reworded help text for a few options.
* bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
* bin/autoscan.in, bin/autoupdate.in: Ditto.
* bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
* bin/autoscan.in, autoupdate.in: Use exclusively the name of the
installed peer executables, only PATH is allowed to resolve it.
Pass `autoconf_dir' via options, not via invisible envvars.
* lib/Autom4te/General.pm (&find_peer): Remove.
* lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
`abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
* man/Makefile.am: Let help2man rely on PATH instead of trying to
find the executables for it.
* tests/Makefile.am: Major cleanup. Too lazy to document...
* tests/atlocal.in: Remove all the obscure envvar manipulations.
We only need PERL.
* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing
--autoconf-dir and others is related to running non installed
Autoconf executables. So don't do that, leave it to...
* tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
* tests/autoscan: New.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
refer to library files: rely on --language.
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.
`die'.
(&END): New.
* bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
`END', as `Autom4te::General::END' will be triggered.
* bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
* bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
system to run `mv', `rm', and `cmp'.
Adjust all the routines to use it.
($log): New file (autoscan.log).
(output): Dump detailed logs into $log, and a shortened version to
stderr.
(&scan_makefile): Refine the regexp catching tokens in the code.
* doc/autoconf.texi (autoscan Invocation): Document `autoscan.log'
and the `configure.ac' checking feature.
(&find_file): Rename as...
(&scan_file): this.
Immediately scan the current file, instead of gathering them, and
later having them handled by &scan_files.
(&scan_files): Merely invoke Find::File.
Adjust.
(&init_tables): Die when a word which is already handled by
explicit macros is mapped to the default macro.
(&print_unique): Remove, inlined in...
(&output_kind): here.
(File::Basename): Use it.
(&output): Sort the CONFIG_FILES.
* acheaders: Normalize.
* acfunctions: Likewise.
(%kind_comment): Add entry for `programs'.
(&output_programs): Use &output_kind.
(&output_functions, &output_identifiers, &output_headers)
(&output_programs): Inline, and remove.
out hashes common for the whole package. Do it in scan_files()
instead.
(scan_makefile): Likewise.
(scan_sh_file): Likewise.
Thanks to Jim Meyering for improved implementation.
From Raja R Harinath.
(@kinds): Use `qw', rather than lots of quotes and commas.
(%generic_macro): Use single quotes around literals.
($configure_scan): Define global, and use it instead of the literal.
Use `warn' in place of `printf STDERR'.
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.
(&init_tables): Use them.
* acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
and include all these headers in here.
Don't specify `AC_CHECK_HEADERS' as it's the default.
locations.
(output_headers): For headers that need to be checked, push either
the specialized macro, or the generic macro call.
(check_configure_ac): Handle AC_CHECK_HEADERS.
or make them private. Make all local variables private.
(find_autoconf): New, moved some code from the top level.
Use %ENV outside quotes to eliminate a warning.
