I had never heard of an OS/2 version of the Alsys Ada compiler before, so I
cannot help you in that line of investigation. In general, older OS/2 programs
run very well on later incarnations of the operating system. The Convenience
packs (v. 4.5) incorporate major changes to the kernel, but I would hesitate to
blame that without further evidence.
Ada on OS/2 is not dead, though. Gnat on Intel PC started out as an OS/2
program, before Windows NT became the major PC operating system. Although ACT no
longer provides ready-made binaries for the OS/2 version of the compiler, newer
versions (up to the current 3.15p) are available thanks to the efforts of Dave
Parsons.
I use gnat 3.14p on OS/2 (v. 4.0) very regularly on fairly large programs and
have never had a problem with it. I have so far not moved up to 3.15p (sorry,
Dave), but I hope to do that one of these days.
Gnat is of course Ada 95, whereas Alsys was Ada 83. That in itself should
present no great problems. There are just a few minor issues which can be easily
fixed. But if any Alsys-specific libraries are involved, that would of course be
a different matter.
Feel free to contact me privately, if I can be of any further assistance.
