I couldn't figure out any other way to check for -Wno-cast-function-type
reliably.  Attempts involving -Werror were defeated by the fact that
some preprocessor variable is redefined somewhere, leading to an error
in all cases.  After spending much time to figure that much out, I was
not interested in spending more to figure out how to resolve it (if that
is even possible).

I could reword the message, something like "whether the compiler might
warn about casting functions to incompatible types."  Would that be
better?
