*Some* C compilers are rude enough about implausible constructs to make lint
redundant. I'd much rather my compiler told me that it had kindly declared an
-extern int toggle_swicth()- for me than (a) wait for the linker to laugh, or
(b) be forced to run an extra program to perform this elementary check.

And no, I'm not advertising HP compilers, either.
