* acgeneral.m4 (AC_PRO, AC_EPI): Rename as _AC_DEFUN_PRO and
_AC_DEFUN_EPI.
Adjust dependencies.
(AC_DEFUN): Remove the not-to-be-released specializing mechanism.
(AC_SPECIALIZE): Remove for the same reasons.
Adjust dependencies.
(_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS, _AC_INIT_VERSION,
_AC_INIT_PREPARE, _AC_CANONICAL_SPLIT, _AC_CHECK_TYPE_NEW,
_AC_CHECK_TYPE_OLD): Define via `define' instead of `AC_DEFUN':
they are not related to AC_REQUIRE in any way.
* acspecific.m4 (AC_PROG_ECHO, _AC_DECL_YYTEXT, _AC_PATH_X_XMKMF,
_AC_PATH_X_DIRECT): Define via `define' instead of `AC_DEFUN'.
avoid cache variable conflicts between AC_CHECK_PROG invocations.
(AC_PATH_TOOL): Fix same bugs as in 6/9/00 fixes to AC_CHECK_TOOL.
Pass correct arguments to AC_CHECK_PATH (different from
AC_CHECK_PROG). Use AC_CHECK_PATH cache variable, not
AC_CHECK_PROG var, and use two variables for two invocations as
above. Quote AC_CHECK_* args.
* acgeneral.m4 (AC_OUTPUT_MAKE_DEFS) <confdef2opt.sed>: Reset the
t flag between each cycle.
* doc/autoconf.texi (Limitations of Usual Tools): Some about the t
flag in sed.
specified, we should still check whether PROG-TO-CHECK-FOR
actually works before returning it when the prefixed program is
not found. Also, fixed a bug where it failed to pass the PATH
argument in the second call to AC_CHECK_PROG.
(AC_F77_NAME_MANGLING): Removed useless comment.
(_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
`[^:][^:]*' to catch file names. The rest of regex is probably
precise enough to avoid incorrect parsing.
* acgeneral.m4 (_AC_COMPUTE_INT_COMPILE): Do not put two shell
variable assignments in one shell command.
* doc/autoconf.texi (Shell Substitutions): Document.
* acspecific.m4 (_AC_PATH_X_DIRECT): Hard code `X11/Intrinsic.h'
instead of using `ac_x_direct_test_include', likewise for `Xt' and
`ac_x_direct_test_lib', `XtMalloc' and
`ac_x_direct_test_function'.
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.

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.

Reported by Alec Wolman.
* acspecific.m4 (AC_FUNC_GETLOADAVG): Check for `getloadavg'
without any additional library.
Fixes Autoconf/109.
