Reorganized. Because files required by this test were created
outside the pair AT_SETUP/AT_CLEANUP, when the test fails and
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.
Reported by Franc,ois Pinard and Rainer Orth.

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.

AC_LINK_FILES to AC_CONFIG_LINKS, with sh-glue code.

with AC_LINK_FILES.
* acgeneral.m4 (AC_INIT_PARSE_ARGS, getopt loop): Always define

`configure var=val' defines ac_optarg=val.
Improve the robustness to shell special characters:
- Use grep when checking that shell variable names are valid.

AC_Member_Member which were complicating more than simplifying.

in...
(AH_VERBATIM): here. Now AH_C_UNSIGNED_CHAR is no longer failing
