and host is irrelevant.
(Specifying Names, Canonicalizing): Remove all references to the
backward compatibility hooks. Rather, collect them all into...
(Hosts and Cross-Compilation): this new section.
* doc/install.texi (System Type): Ditto.
* lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
that `--host' implies cross-compilation.
* lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
useless.
(_m4_foreach): Define the variant with immediate evaluation so
that it contains exactly the items, not an expression which
evaluation is the current item.
(m4_re_string, m4_re_word): Don't over quote them.
`foreach' loops immediately evaluate them.
* lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
$*. This is the n-th time I change my mind, but hopefully this is
the last...
(m4_lquote): New.
(m4_text_wrap): Use m4_foreach, which is finally correct _and_
efficient.
(m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
it was only a hack for m4_text_wrap.
(m4_car2): Remove, replaced by...
(m4_cdr): New.
(_m4_foreach): Adjust.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
m4_bpatsubst for clarification.
AC_PREFIX_PROGRAM fails with dashed program names
* lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
variable when looking for the prefix program.
Now it also works for shell variables.
Describe HP-UX cc bug workaround more accurately.
* lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
not unsigned long.
* tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
cross-compilers, too. This undoes some of the most recent change
to this file.
optional are the sum of the previous files on the command line'.
Also, pass `--reload-state=' on them, so...
(handle_m4): don't.
* lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
(M4sh): Rely on M4sugar.
(Autotest, M4sh, M4sugar): Use frozen files.
AUTOTEST_PATH *after* it was set.
Don't put `.' in the PATH: the user should be precise and `./' if
needed. In addition, given that the test suite does some `cd', if
`.' is in the path, the `tested programs' sections will report
programs found in the test suite's directory, while during the
tests (performed in their own directory), these programs are no
longer visible. In other words, the results is confusing and
useless.
* tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
