An Interface question

[ocremel@idiom.com (Olivier Cremel)]

I'm using an m68k OS (AmigaOS) where system calls expect arguments in
registers, not on the stack as normal convention has it.

I've been reading all Ada95 documents I have but I haven't found a way
to express that convention either for me to access a system call  or
to provide one.

Short of writing assembly wrappers, is there a way ?

Thanks,
Olivier.
