Moving most of the task of creating config.h.in from sh to m4.
Getting rid of acconfig.h by supply a major new family of macros:
AH_* which make it possible to insert arbitrary text into
config.h.in.
* autoheader.m4: Major rewrite: introduction of a set of macros
AH_ that produce code into config.h.in. There are two sets of
macros: generic macros, or specialized, documented below. The
basic idea is that an AC_FOO macro which needs an entry in
config.h.in should have a sibling AH_FOO which expands into that
entry. In a near future, these macros will be moved next to their
siblings.
* autoheader.m4 (End section): Bind AC_ macros to their
AH_siblings.
* autoheader.sh: Remove the sections in charge of SYMS, TYPES,
FUNCS, HEADERS, LIBS and DECLS: autoheader.m4 is now in charge of
these.
* autoheader.sh (options): Added -d, --debug, which does not
remove the temporary files.
* autoheader.sh: Instead of redirecting stdout to the output
stream, always output to a temporary file. This allows to change
slightly the consistency check: before autoheader would check that
each non documented AC_DEFINE is templated in an acconfig. Now it
just checks whether the template is in the output file.
* acconfig.h: Completely emptied, the remaining templates
(_ALL_SOURCE, __CHAR_UNSIGNED__, F77_FUNC, F77_FUNC_,
HAVE_STRINGIZE, and STACK_DIRECTION) are now either associated to
their AC_DEFINE, or to one of the new AH_ macros.

(AC_FOREACH): New macro, to perform m4 loops on shell lists (i.e.,
list='item_1 item_2 ... item_n').
* acgeneral.m4 (AC_DEFUN): Now accept two other optionnal
parameters: the name of the macro which is specialized here, and

as first argument.

(AC_VAR_IF_SET): New `ifelse' macro.

portably in a sed \(\) group.
(Particular Programs): Document new optional argument to AC_PROG_CC,
AC_PROG_CXX and AC_PROG_F77. Document additions to the Fortran 77
compiler search list.
