Thanks for your report.  Two questions:
Does it harm to mention $@ if the macro does not take any arguments?
(I think not, but neither Autoconf nor m4 info seem to be very elaborate
on this).

AU_ALIAS seems not to be part of official Autoconf interface.  So I'd
take the second form then, right?

Thanks,
Ralf
