Porting Ada 83 on AIX to Ada 95 on NT

[rh@signal.dera.gov.uk (Roger Hoyle)]

I'm a newbie Ada programmer with a reasonable background in other
languages.

I'm currently trying to get at some [complicated] functionality currently
in Ada 83 on AIX and can see two routes forward at the moment...

i) Compile it on AIX using the original compiler and call it [somehow :]
across a network when required.

ii) Compile it on NT using a 83/95 (?) compiler and call it locally when
required.

The application uses the Posix_Io package and I haven't tracked down a
validated version on NT. 

Could anyone advise me if I'm being silly or whether I actually have a
reasonable chance of compiling it under NT, and which compilers would be
worth giving a try?

Any help gratefully received,

cheers

rog.
