Yes - since this afternoon ;-)

Unfortunatly I use aclocal 1.7 and do not have aclocal 1.4 to
regenerate the files - and using 1.7 would force newer autoconf :-(.

I tested the patch with handediting configure and aclocal.m4 and it
worked fine.  Can somebody else with the right tools test and commit
this for me, please?

Thanks,
Andreas
