	Require GNU m4 1.4 (well 1.3 in fact).

	Because we are ready to handle the case where there are no frozen
	files, we *have* to pass a -I, which is dangerous in conjunction
	with the silent including of `aclocal.m4': you may include things
	that were not expected.  Since anyway handling pre 1.3 complicates
	the task, just require an m4 which supports reloading of frozen
	files.

	* acspecific.m4 (AC_PROG_GNU_M4): Check for --reload.
	* autoconf.sh: Likewise
	* autoheader.sh: Likewise.
	* configure.in: Explicitly state the m4 version you want.
