Interface can be made somewhat automatically checkable.

For example:
void a(int);
void b(int, int);
void b(int, char);

Is compatible with:
void a(int);
void b(int, int);

And this can be checked automatically - real header must have all
headings that interface describes. Microsoft has actually done good
work in C# on that topic -- first place where i saw something like
that after thinking about it myself :) This MS version is feature of a
language, of course, not a feature of compiler. Anyway, that might
give an idea.

I'm actually sure that this all can be calculated up from sourcecode
and bindep would be after that a check if cpu didnt calculate
something wrong :P Another question, how difficult it is and is it
worth the time.

Theory is when you know something, but it doesn't work. Practice is
when something works, but you don't know why. Programmers combine
theory and practice: Nothing works and they don't know why.
