#1 Do not compile on windows with mingw

[Anonymous]

There are some predefined symbols missing that prevent it to compile on windows with mingw.
I tryied using a macro wrapper on then but some of then are not defined on windows so probably we need define an enum for then.

#ifdef _WIN32
#define P_M(a) WSA##a
#else
#define P_M(a) a
#endif
