(Limitations of Usual Tools): Add mkdir section.
* lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
(AS_MKDIR_P): Require it. Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
Create at_test_all by a series of assignments,
not by a single assignment of a long string. The latter causes ksh
version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
presumably because of a buffer overrun.

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.
