Frédéric Bron a195bf86a2 Make compilation with mingw-w64 possible with -std=c++17.
The definition of macros min and max in include/wx/msw/wrapgdip.h
b/include/wx/msw/wrapgdip.h was clashing with the new bessel functions
that use std::numeric_limits<T>::min/max.

So #include <cmath> before #include <gdiplus.h> and use using
declarations of std::min and max instead of macros.
