GetProcAddress returns all function pointers as if they were of type 'int
(*)()', because it has to return a pointer to some kind of function, but it
can't know what actual prototype the function has, so it uses the simplest.
In your program, where you /know/ the actual type of the function, you
need to cast the result returned from GPA:
void (*init)() = (void (*)()) GetProcAddress(h, "cygwin_dll_init");
