Hi,
Thanks, That explains it.
The NetBSD folks said they follow the Sys V ABI but after I saw what Mac OSX was doing I got worried. The two ABI's must be very similar since so much was the same.
Do you have a reference or link to PowerOpen ABI documentation or anuything that explains the differences?
Thanks,
Kevin
