Use test instead of sed.
<automake>: If automake is used, always run it: it has its own
mechanism not to update if unneeded.
* acgeneral.m4 (AC_SHELL_DIRNAME): When using m4 the argument
is named `$1' not `$dir'.
When using m4 you ought to quote properly.
When using m4, you should check that there are not too many shell
quotes (inside the macro itself, and where it is called).
When you do this, Autoconf, hm, works better.

Handle `-ofile', not only `-o file'.
* doc/autoconf.texi: Free Franc,ois Pinard from iftex and ifinfo,
use @,c.
Don't use `@code{m4}' when you mean M4, just as you shall not say
`@code{cc}' when you refer to the C language.

Fixes Autoconf PR/134, from Raja R Harinath.

lf95 (Lahey/Fujitsu Fortran) and pgf77 (Portland Group Fortran)
(_AC_PROG_F77_G): Some Fortran compilers produce stdout/stderr
output even if no errors occur - check exit status rather than
output.
* acgeneral.m4 (build_alias): Set to host_alias if --build is not
given but --host is, and enable cross-compile auto-detection. If
both are, and are different, enable cross compilation.
(AC_CANONICAL_HOST): Adjust help message.

Pass --verbose to the tools.
Avoid using plenty of variables, just append to existing

Fix this bug, implement the solution provided by Axel Thimm,

(_AC_PROG_F77_GNU): Use `.f' not `.fpp' which is not properly
processed by Abysoft's Fortran compiler.
Reported by Mark Elbrecht.
* autoconf.sh <trace> (trace2m4.sed): Use `..*' instead of

Use `no', not `NO' for ac_x_includes and ac_x_libraries.
Adjust dependencies.

of places where headers and libs might be.
(AC_PATH_XTRA): Don't quote the argument of `case'.

`yo-man-i-am-the-all-mighty-AVt0h3Ad3R-eh-eh' and the other tools
want to trace, they might stupidly invoke the program named
`autoconf' instead. Pfff, stupid scripts :)
* Makefile.am (editsh): Transfer the names of the install
`autoconf' and `autoheader'.
* autoconf.sh: Add a missing period at the end of the comment
# Parse command line
Make sure to have a ChangeLog much longer than the patch.
* autoheader.sh: Use the right `autoconf'.
* autoupdate.sh: Likewise.

is because the DJGPP `ln' emulates soft links for executables by
generating a stub that in turn calls the real program. This
feature also works with nonexistent files like in the Unix
spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
which will attempt to call 'X.exe'. But this feature only works
for executables. Fix it.
* acspecific.m4 (AC_PROG_LN_S): Create a sample file and use it to
test `ln -s'.

AC_CANONICAL_SYSTEM was run, then the value of `$build' given by
the user was saved into `$build_alias', and `$build' was
normalized using `config.sub'.
Now, let `--build' set `$build_alias' so that scripts with or
without `AC_CANONICAL_BUILD' have the same semantics. This allows
to use `AC_CHECK_TOOL' without requiring `config.guess' and
`config.sub' (which was bizarre anyway).
* acgeneral.m4 (_AC_INIT_PARSE_ARGS): --build, --host and --target
set `build_alias' etc.
After the option handling, set host to $host_alias etc. for
bugward compatibility.

computes `$foo_os' etc.

given, not when `$host != $build'.

* autoconf.texi (AC_CHECK_MEMBER, AC_CHECK_DECLS, AC_CHECK_TYPES):
Adjust their documentation.
(AC_INCLUDE): Undocument.
* tests/semantics.m4: Adjust.
* tests/actest.m4: Rename as...
* tests/aclocal.m4: this.
* tests/atspecific.m4: No longer include actest.m4.
* tests/torture.m4: Likewise.
* tests/Makefile.am: Adjust.
(AC_REPLACE_FUNCS): Use AC_LIBOBJ.
* acspecific.m4 (AC_FUNC_MKTIME, AC_FUNC_MEMCMP,
AC_STRUCT_ST_BLOCKS): Use AC_LIBOBJ.
* doc/autoconf.texi : Adjust so that the user is not encouraged to
use LIBOBJS directly.
(Generic Functions): Document AC_LIBOBJ_DECL and AC_LIBOBJ.
Suggested by Jim Meyering.
* acgeneral.m4 (_AC_SHELL_TMPDIR): New macro.
(_AC_OUTPUT_CONFIG_STATUS): Use it.
Use more quoted here docs to improve readability.
Compute `$me' and use it in the error messages.
Define `$configure' and `$configure_args' to avoid continuously
mixing the uses of `configure' and `config.status' evaluation in a
single line.
Define `$SHELL' and use it.
Simplify all the unjustified `[$]foo' into `$foo', the quotes
are needed only for `$[1]', `$[@]' etc.
Replace all the uses of `ac_cs_root' with files in the tmp dir of
`config.status'.
Remove a few `rm' covered by the removal of the `$tmp' dir.
Let `config.status' support `--debug'.
(_AC_INIT_PREPARE): Avoid the leading space in `ac_configure_args'.
* doc/autoconf.texi (Invoking config.status): Adjust.
Unix 4.0x and 5.0 because `"$@"' expands into an empty parameter
(instead of nothing) when there are no positional parameters.
From Nicolas Joly.
* acgeneral.m4 (AC_CHECK_PROG, AC_CHECK_PROGS): Prefer
`$$1' to `[$]$1', `$foo' to `[$]foo', `$[1]' to `[$]1', and
`${1+"$[@]"}' to `"[$]@"'.
* autoheader.sh: No longer try to select the needed paragraphs of
`acconfig.h', just dump everything into `config.h.in'.
Implement support for `--warnings'.
Warn the users that these auxiliary files are obsolete when `-W
obsolete'.
* doc/autoconf.texi (Invoking autoheader): Adjust.
Reported by Jim Meyering.
* autoheader.sh: Trace AC_DEFINE and AC_DEFINE_UNQUOTED to build
the list of $syms which are defined.
* tests/tools.m4 (autoheader): New test.
* acgeneral.m4 (_AC_SH_QUOTE): Don't double quote. Escape the
double quotes too.
(_AC_ECHO_UNQUOTED): Don't double quote :).
(_AC_ECHO, _AC_ECHO_N): Quote the call to _AC_SH_QUOTE.
The autoheader chain needs to be adjusted.
* acgeneral.m4 (AH_VERBATIM): Just pass two arguments to AH_OUTPUT
instead of trying to build what `autoheader' needs: let it handle
the format by itself.
* autoheader.m4: Adjust.
s,tmp/config.h,tmp/config.hin.
The adjustment revealed that `autoconf --trace' is not robust to
single quotes in its argument.
* autoconf.sh: Fix this issue.
Rename the escape `$*' as `$%'. Implement `$@'.
* doc/autoconf.texi: Adjust.
changing value. On the `configure' script of the fileutils:
mawk '{ sub (/foo/, foo++) }' -> 14s.
mawk '{ if ($0 ~ /foo/) sub (/foo/, foo++) }' -> 0.03s.
mawk '{ sub (/foo/, foo) }' -> 0.03s.
* autoconf.sh (task script, AWK script): Run `sub (__oline__,
oline)' only in the lines that match `__oline__'.
Suggested by Paul Eggert.
section.
Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning
of the installation directories'.
In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.
Reported by Kathryn Hargreaves.
Move --host before --build.
Fix a test on `$ac_init_help' which was not updated.
* tests/atspecific.m4 (AT_TEST_MACRO): Don't check `env-after' if
the file does not exist, which may happen when a `configure' exits
brutally.
* tests/semantics.m4 (AC_CHECK_MEMBERS, AC_CHECK_TYPES): ANSI C++
forbids members named like their hosting struct, so don't do it.
Use `#' to denote Autoconf comments, not `dnl'.
Put a few `' here and there to avoid misfontification and
misindentation.
Use your base name when reporting errors.
(parse_args::usage): Use $0, use the same order as the other
executables.
(parse_args): Don't dump `--help' on cmd line errors.
* doc/autoconf.texi (Old Macro Names): Rename as...
(Old Macros): this. Change the @table enumeration into a list of
@defmac.

AC_XENIX_DIR): Move their descriptions into here.
Kill a few TeX warnings.

(AC_CACHE_SAVE, AC_OUTPUT): Use it.
(AC_OUTPUT): Dump confdefs.h into config.log.
(_AC_INIT_PREPARE::config.log): Name the package being configured
if you can.
newbies accidentally use a stale cache file.
* acgeneral.m4 (_AC_INIT_PARSE_ARGS): Set cache_file to /dev/null
to disable caching by default.
(_AC_INIT_HELP): Adjust the --help message.
(AC_CACHE_LOAD, AC_CACHE_SAVE): Don't print "loading/updating
/dev/null" messages.
* autoconf.texi: Note that caching is disabled, how to enable it,
and that `./config.cache' is the traditional name of the cache file.
* install.texi: Likewise.
