He feels that since Windows95 is a single user system, he should be able to

This is nothing to do with GNAT. Anything that can be done in this regard
can most certainly be done using GNAT, since this is not a language
dependent issue at all. Some glue code may be needed at some level, in
writing the necessary device drivers, which could for example be done
with package Machine_Code, or alternatively this may well be a case in
which a mixed Ada-C approach would make sense.

Certainly there is no feature that needs adding to GNAT to support this!
I would certainly be opposed to adding some Win-95 specific rubbish to
Ada or GNAT. We will let Mr. Gates do that if he ever feels that universal
use of Ada is threatening the ability of Microsoft to lock out non-MS
users :-)
