From Raja R Harinath.
(@kinds): Use `qw', rather than lots of quotes and commas.
(%generic_macro): Use single quotes around literals.
($configure_scan): Define global, and use it instead of the literal.
Use `warn' in place of `printf STDERR'.
functions, no longer use `&' to call functions as it disables
prototype checking, topological sort so that functions are defined
before being used, and put an Autoconf like nice comment to
describe the functions.
(output): Accept an CONFIGURE_SCAN parameters, and open CONF.
* acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_INSTALL for internal
computations, and therefore use INSTALL where ac_given_INSTALL
was used.
(_AC_OUTPUT_SUBDIRS): There is no point in computing INSTALL in
here. It's not even used.
Reported by Ralf Corsepius.
* tests/aclocal.m4 (AC_STATE_SAVE): It is ok to modify
CONFIG_STATUS, DEFS, prefix and exec_prefix.
It is OK to produce config.* files.
* tests/atspecific.m4 (AT_CONFIGURE_AC): Save the env *after*
AC_OUTPUT to check that it doesn't break anything by itself.
* tests/torture.m4 (srcdir): New test, from Ralf Corsepius.
* acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_top_srcdir and ac_srcdir
to preserve srcdir and top_srcdir.
Remove any use of `ac_given_srcdir' as `$srcdir' being preserved
is usable.
* acgeneral.m4 (_AC_INIT_DEFAULTS_FDS): Don't check for $silent,
tie AS_MESSAGE_FD to stdout unconditionally.
(_AC_INIT_PARSE_ARGS): If $silent redirect AS_MESSAGE_FD to
/dev/null.
* tests/base.at (AC_CACHE_CHECK): New test.
(&init_tables): Use them.
* acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
and include all these headers in here.
Don't specify `AC_CHECK_HEADERS' as it's the default.
locations.
(output_headers): For headers that need to be checked, push either
the specialized macro, or the generic macro call.
(check_configure_ac): Handle AC_CHECK_HEADERS.
variables in Makefiles, and drives autoscan to require unneeded
programs.
* acgeneral.m4 (_AC_INIT_PREPARE): Don't AC_SUBST CFLAGS,
CPPFLAGS, CXXFLAGS and LDFLAGS.
(AC_ARG_VAR): AC_SUBST the var.
Document it only once, even if there are several different docs.
* aclang.m4 (AC_PROG_CPP): Declare CPP and CPPFLAGS to AC_ARG_VAR.
(AC_PROG_CXXCPP): Declare CXXCPP and CPPFLAGS.
AS_IF([AC_TRY_EVAL(ac_link)]) instead of AC_LINK_IFELSE to
avoid depending on ac_exeext before it's found.
(AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Check for the
executable extension BEFORE checking whether the compiler
works, as that test depends on a correct ac_exeext.
or make them private. Make all local variables private.
(find_autoconf): New, moved some code from the top level.
Use %ENV outside quotes to eliminate a warning.
`Makefile.in' is present.
Factor the simplification of $name.
(&scan_makefile, &scan_sh_file): Instead of counting the number of
occurrences where a program/makevar is wanted, register file:line.
Adjust the verbose output.
(&check_configure_ac): Report the location where the macro is required.
values.
(%needed_macros): New.
(&check_configure_ac): New. Call it.
(&output_libraries): Eve out from &output_programs.
(&print_unique): For the time being register in %needed_macros
only argument less macros.
