   Doesn't the declaration "register char *pt;" mean "a pointer to a
register," in fact?  Can you tell me what a pointer to a register is?
Supposedly, that kind of (presumably) illegal declaration is ignored,
but I can see where a writer of a <$100 compiler might not handle it
correctly.  That's no excuse, of course...
