if condition for win32 unary function fix

[cebarboza]

Added condition for unary function if WIN32

#ifdef _WIN32
struct AndJibu : public std::unary_function<int, void>
#else
struct AndJibu : public std::__unary_function<int, void>
#endif

Changes the condition to APPLE and it seems to pass the checks for tests, macos, win, linux and linux old like that.

#ifdef __APPLE__
struct AndJibu : public std::__unary_function<int, void>
#else
struct AndJibu : public std::unary_function<int, void>
#endif
