first, thanks to Ken the bug report and for his support.

When I unpacked the tarball which Ken mailed me, I saw the reason:
the system was too quick, and autoheader, called without --force,
thought that the previous autom4te.cache/* files were up-to-date.

So this was a bug in the testsuite, not in the Autoconf itself.

The fix is to add --force to the autoheader call.

Actually, I think there are more places where this problem can appear.
I added --force to AC_CHECK_AUTOCONF; thus all autoconf calls
are with --force.

I committed the patch, as attached to this mail.

Please note that if "autoconf --force" regenerates autom4te.cache/*, then
the subsequent autoheader works: autoheader always creates config.hin,
but the problem was only with autom4te.

Couldn't autom4te also compute some checksums of the input files?

(If Bruno is here, he would suggest that the autom4te caching should be
swiched off by default, right?)

Have a nice day,
        Stepan
