Re: [Mingw-w64-public] wspiapi.h:50:20: warning: cast between incompatible function types from ‘void (__attribute__((stdcall)) *)(struct addrinfo *)’ to ‘int (__attribute__((stdcall)) *)()’ [-Wcast-function-type]

I thought the 'correct' way to do this is by casting to (void(*)(void)), at
least that's how the gcc docu says this warning should be suppressed:
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wcast-function-type

Yes, it makes sense in this case.

However we notice that `GetProcAddress()` can also be used to obtain a pointer to a dllexport'd object, so `intptr_t` or `INT_PTR` might be deemed a unified solution. (And at the ABI level it doesn't make a difference to use any pointer type.)
