`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.

The autoheader chain needs to be adjusted.

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 `$@'.

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__'.

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

misindentation.
