Use `no', not `NO' for ac_x_includes and ac_x_libraries.
Adjust dependencies.
(_AC_PATH_X_DIRECT): Introduce ac_x_header_dirs to factor the list
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-AVt0c0nF-eh-eh'. But when
`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.
* autoreconf.sh: Likewise, and for `autoheader' too.
Simplify the handling of localdir and AC_MACRODIR.
* ifnames.sh: Formatting changes.
cannot produce object code.
* aclang.m4 (AC_PROG_F77): Remove f2c from the search list.
* doc/autoconf.texi: Excise mentions of f2c in AC_PROG_F77 docs.
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'.
* doc/autoconf.texi (Obsolete Constructs): Move right after
`Recreation a Configuration.
(Invoking autoupdate): Be a subsection of
`Obsolete Constructs'.
(Upgrading): Demote from chapter to section.
Be a section of `Obsolete Constructs'.
Rename as `Autoconf 1'.
Use this technology to compute `sizeof' even when cross-compiling.

* aclang.m4 (AC_LANG_BOOL_COMPILE_TRY,
AC_LANG_BOOL_COMPILE_TRY(C), AC_LANG_BOOL_COMPILE_TRY(C++),
AC_LANG_INT_SAVE, AC_LANG_INT_SAVE(C), AC_LANG_INT_SAVE(C++)): New
macros.
* acgeneral.m4 (_AC_COMPUTE_INT_COMPILE, _AC_COMPUTE_INT_RUN,
_AC_COMPUTE_INT): New.
(AC_CHECK_SIZEOF): Use them.
Check whether the type exists beforehand.
* tests/semantics.m4 (AC_CHECK_SIZEOF): Strengthen.

* acspecific.m4 (AC_FUNC_GETLOADAVG): Check for `getloadavg'
without any additional library.
Fixes Autoconf/109.
classes with `case'. Use `expr' instead.
Suggested by Paul Eggert.
* doc/autoconf.texi (Limitations of Builtins): Explain expr, the
`x' trick, and negated character classes.
* acgeneral.m4 (AC_CHECK_TOOLS): New.
* aclang.m4 (AC_PROG_CXX, AC_PROG_CC, AC_PROG_F77): Use new
AC_CHECK_TOOLS macro instead of AC_CHECK_PROGS so that a cross
compiler is found by default with --host.
* doc/autoconf.texi (Generic Programs, Manual Configuration):
Describe new AC_CHECK_TOOLS macro. Fix unclear working about
AC_CHECK_PROGS.
* tests/Makefile.am (FILTER_MACROS): Adjust.
* acspecific.m4 (AC_XENIX_DIR, AC_DYNIX_SEQ, AC_IRIX_SUN,
AC_SCO_INTL): Wake up a few zombies.
* doc/autoconf.texi: Adjust.
* tests/aclocal.m4 (AC_ENV_SAVE): Likewise.
(Special Shell Variables): Adjust.
(Shellology): New section. Introduce bash and zsh.
(Special Shell Variables): Some data on NULLCMD.
(Quotation Thumb Rule): Rename as
(Quotation Rule of Thumb): this.
* acgeneral.m4 (AC_SHELL_UNSET): Remove.
(AC_SHELL_UNSETENV): Rename as...
(AC_SHELL_UNSET): this.
(_AC_INIT_PREPARE_ENVIRONMENT): Prepare bash and zsh.
Adjust to AC_SHELL_UNSET.
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 $host_alias etc. for
bugward compatibility.
(AC_CANONICALIZE): Mutate into...
(_AC_CANONICAL_SPLIT): this, which does not canonicalize, it just
computes `$foo_os' etc.
(_AC_CANONICAL_THING): Remove, too confusing.
(AC_CANONICAL_BUILD): Adjust.
Do not assign any value to `build_alias', just compute `build', and
`build_{cpy, vendor, os}'.
(AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Likewise.
(AC_CHECK_TOOL_PREFIX): Fire your rule when `$host_alias' is
given, not when `$host != $build'.
* acgeneral.m4 (sinclude): Fix typo.
Now work with other languages than C and C++.
* acspecific.m4 (AC_EXEEXT, AC_OBJEXT): Use
AC_COMPILE_IFELSE/AC_LINK_IFELSE and AC_LANG_PROGRAM instead of
ad hoc code.
Use `$ac_ext' instead of listing `.c', `.C' etc.
Use AC_CACHE_CHECK.
* doc/autoconf.texi (System Services): Adjust.
