Re: differences between ada95 using O32 and N32 on SGI's

Talk to your compiler vendor! :-)

Your question is an implementation-specific one.  You didn't even specify
what compiler you're using.  But in any case, it's probably a technical
support question for them -- I'd be suprised if anyone on c.l.a. can offer
any insight...

But good luck!
