Re: Handling signals in ADA

["David C. Hoos, Sr." <david.c.hoos.sr@ada95.com>]

Remember that in the context of the original inquirer's question,
he was using an OS with Unix-style signals, so he couldn't have been
talking about a DOS implementation where Unix-style signals
do not exist.

I have yet to see an Ada95 compiler targeted to a platform with
Unix-style signals that does not support the correspondence between
signals and interrupts.  Perhaps there is one or more, but I've not
seen them.  Do you know of any?
