Well.... if you read your compiler's library code, you'll find they import
lots of stuff from the C runtime libraries.

I've done mmap in Ada83 on IRIX (4.01 through 6.2) with no problems, except
once
SGI changed some #defines in a header file, and we didn't have an automated
way to do the header translation, so we missed it.

The way we do it today is to use the IEEE-standard POSIX/Ada95 bindings
provided by Florida State University and supported by ACT.
Perhaps if it's genuine POSIX, and meets the requirements of the
IEEE-standard,
maybe the fact that underneath it's really imported will be acceptable to
your "instructor."
