Will you be putting it up anywhere?  It might be nice to have compiler
independant versions of things like this.

Several of the biggy useful tools like gwindows, gnatcom, and possibly
gtkada (with emphasis on the possibly) use gnat dependant features, which
deters their use in other compilers.  It'd be interesting to see how much
code is actually gnat dependant in those tools.

To me it's just clutter, but what do I know?
