oh, please.  70-80% of my users use libraries that someone else
compiled for them.  giving meaningless warnings is a great way to
make them question the quality of the software (I had enough of
that when 2.1 started complaining about shadowed globals), but
it won't help them a bit.

if the message is meant for me, please make sure I see it.

the C compiler/linker has no problem doing that.  but I cannot
guarantee that every library I've ever written has a test suite
that tests every piece of the library, or that the test suite is
set up to look for warnings (doctest won't catch them, for
example).
