Ad multinauseam, Paul. If you hark back to your Latin lessons at school,
nausea is of the first declension, so that the accusative is -am.
Actually, I'm not sure that the ad + accusative is correct, as the
dative alone should be sufficient. The Latin nausea comes from the Greek
nausia, in turn from naus, ship, showing that we are all at sea, which
is full of ionic contaminants that cause dendrites :-)

Seriously, the IPC should have an FAQ of issues raised in the forums -
save us a lot of fingertip-wear, provided that they were read before
people rushed to their keyboard.
