To tell the truth, I'd rather it have been a fatal compile error.  That
would have been more helpful to me that a warning and Doing The Right
Thing.

And so I shall, believe me.  (that's what I get for hacking way past my
bedtime :-)

Agreed, as does the help function in TC IDE, and the THELP TSR.
Unfortunately, I got one of those occasional recto-cranial displacements
and neglected to look at them.

I'll see if I can get Turbo to act similarly, although I've already had
dos.h fail with the 'ANSI keywords only' directive enabled.  I suppose I
should just chuck DOS for an operating system.  (it'd be easier to get
GCC, too)

Thanks for the help!
