--- Comment #1 from Eli Friedman <sharparrow1 at yahoo.com> ---
This is how C works with a traditional compiler; each object file is generated
independently, so the tools never notice the prototype of a function doesn't
match.

If you're interested, there are some people experimenting with adding
information to the compiled object file about things like function prototypes,
in the context of checking the C++ ODR rule (which is closely related); I think
there's a recent thread on cfe-dev.
