* acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
m4_define, not define). 4mn.
(_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you

If instead of using m4, you use an `associative array' plus a
wrapper (current implementation), it falls to 2mn.

CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
diversion, because it is AC_OUTPUT_FILES which undiverted the
AC_SUBST sed script at its proper place, otherwise it would have
been undiverted at the end of `configure', leading to an sh syntax
error.
Now that we no longer use a diversion, we don't need to call
AC_OUTPUT_FILES if useless.

Any character before the colon is accepted because network drives
can be assigned characters outside the [a-zA-Z] range. DOS-style
relative paths (?:foo/bar) are also considered absolute for

* tests/torture.m4 (config.status under extreme conditions):
Reorganized. Because files required by this test were created

autotest extracts this test, the `debug' script does not contain
the files it needs. Now AT_SETUP/AT_CLEANUP encloses the full
auto contained section.

* acgeneral.m4 (AC_OUTPUT_HEADERS): Renamed as...
(_AC_OUTPUT_HEADERS): this. All callers changed.
Don't mess with changequote, just quote properly.
Bug 1. Because of the `#' in `ac_dA', the quotes <<>> were not
removed, and therefore the sed script contained `<<define>>'
instead of `define'. Now that the block is properly quoted, there
is no need to quote `define'.
Bug 2. Once a `#define' substitution performed, we were branching
to the top of the sed script (`t top'). This resulted in an
endless substitution of `#define foo 1' to `#define foo 1'.
Branching is not enough: you also have to fetch the next input
line, i.e., use `t' instead of `t t' in ac_dD, and don't output
`: top' in `config.defines'.
Though it was correct for `#undef' templates, just apply the same
transformation to `ac_uD' and `config.undefs'.
Bug 3. Don't try to preserve what was behind the value in the
template, since on
#define NAME "bar baz"
it leads to
#define NAME 1 baz"
Now `ac_dB' catches everything behind the NAME (making sure there
is at least a space) and `ac_dC' only outputs a space.
* tests/torture.m4: Check that various forms of `#define' header
templates are properly handled.
* acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): It is smarter to use a
quoted here doc to output the section providing defaults for
CONFIG_*.
Don't rm the CONFIG_FILES here but in..

Hm, actually, no, just don't remove them at all, let the newly
