It does seem counterproductive. Unfortunately autoupdate doesn't actually understand m4 syntax so it often runs into problems similar this one. I'm sure it could be improved to better handle this specific case, though. But for the same reason, you should be able to work around the problem just by quoting differently, for example: AU_ALIAS([BNV_][HAVE_QT], [AX_HAVE_QT]) Cheers, Nick
