That's GNAT-specific stuff; it's not part of Ada. It's best to stick with
standard Ada, especially when doing so is easy (as in this case). Those of
us that use other Ada compilers at least part of the time will be able to
use your software if you do.

One of the nice things about Ada 95 is that interfacing code like this can
easily be written to work with any Ada compiler for the target. That was the
whole idea behind Claw; the fact that only a few lines of Claw's code needs
to be adjusted to particular compilers (mostly for bug workarounds) shows
that Ada 95 code really can be portable.
