Sorry, I don't want to seem too pushy on this issue, but I consider -Wmissing-prototypes a really important issue. It bit me really badly once and has been a hobby horse of mine ever since. The reason its important is that in C (C++ is a different matter which I'll explain later), if no prototype for a function is seen, the compiler assumes that the caller will get the number, order and type of the function arguments correct. However, if the caller gets it wrong (or the function definition changes) really bad stuff happens (ie really horrible, hard to track down bugs). In addition, if you don't include the header, automake doesn't realise that the caller depends on the header (and hence the function definition). In C++ its a different matter. Because of function overloading, the C++ linker does the checking of function arguments, order and count and doesn't allow you to mess up. Thats why the -Wmissing-prototype flag is C only. Hope this helps.
