warning message printed when only --host is given. Fix printing
of multiple compiler cache values, use PATH argument.
* aclang.m4 (AC_LANG_COMPILER_WORKS): Print the cross compile
status, fix problem where two results were printed at once.
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.
(cross_compiling): Enclose in quotes when testing.
* aclang.m4 (_AC_LANG_COMPILER_WORKS): If cross_compiling is
maybe, set it to yes or no depending on the result of the
execution test.
* doc/autoconf.texi: Document the change.
* doc/install.texi: Likewise.
AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
of an m4 variable to store what must be done, so that sh
conditionals are honored.
(_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
* tests/semantics.m4: Test the four AC_CONFIG sisters.
* doc/autoconf.texi (Configuration Actions): Promote the use of
literals, show it works properly with sh conditionals.

because it produces TEST3; TEST2a; TEST2b; TEST1.
Fix this bug, implement the solution provided by Axel Thimm,
and test AC_REQUIRE.
* acgeneral.m4: Document this implementation.
(_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
are emitted in the same order as they are expanded.
(AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
particular the top level).
* tests/base.m4 (AC_REQUIRE): New test.
* 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.
* 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'.
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'.
