Right. If that is 16-bit assembly code, there is no chance that it will work
with a 32-bit compiler like GNAT.

An option would be to port it to Janus/Ada 83 instead, we still support the
16-bit version of that.

Otherwise, you'll have to get rid of the assembler code, replacing it by Ada
(hopefully) and possibly in-line assembler. You may need to find someone who
understands 8086 assembler to do that. (I may be available. :-)
