Re: Bootstrap with -Wmissing-prototypes doesn't work for C++

-Wmissing-prototypes means that if the compiler sees a globally visible
function definition, it warns if no previous definition of the function
was seen. This is a way of ensuring that the file which defines a
function #includes the header file which declares the function, thus
ensuring that the definition matches the declaration. Although the name
is wrong for C++, the option is meaningful for C++ just as it is for C.
(I actually sent a patch implementing this option to RMS back when I was
first starting to work with gcc, although I think he rewrote it.)
