Gcc is *very* permissive with pointers to functions. If we declare them as function, it understands that we meant pointer to functions. If we try to call a pointer to function, it understand we want to dereference that pointer before the call. Visual C++ is not that cleaver (what a surprise). So, try to sanitize a bit the situation by doing the Right Thing without expecting the compiler to understand what we really meant in the middle of what we said. (sorry for the huge diff)
