or aspect Unreferenced, or if you're prepared to accept GNAT extensions
anyway, just call the not-referenced variable Dummy, or Unused, or .. I
listed the relevant variable names upthread.

I suspect you _won't_ get a warning if you do reference a variable named
Dummy, but at that point it should be pretty obvious that something's
wrong.

I think any compiler needs some facility like this, at least if it has
any pretensions to interfacing to foreign languages; but it probably
won't be the same as Ada's.
