You can always trap warnings via $SIG{__WARN__}.

The problem with Apache::Reload is that it may leave around some modules
compiled with the old constant, and compile newer ones with the new value
of the constant. (Remember that constants are inlined.) That's why I'm
not confortable with having this warning easy to disable.

(Maybe an ad-hoc optional $SIG{__WARN__} handler could go
into Apache::Reload ?)
