I added -Wstrict-prototypes to the CFLAGS for my own package, not
Guile itself. GCC, by default, does not produce warnings in system
headers (i.e. libguile.h & depends). If those functions have such
parameter types, though, missing `void' where it should be, then you
would get warnings there while compiling Guile, I should think.
Then again, the warnings I turn on would probably complain all over
the place.

I believe this, however, would eliminate almost all the benefit of
type-checking of function pointers in the first place.
