The compiler errors you sent me said that they weren't declared in
scope. Not undefined reference. Likely your mingw-w64 headers are

Remember that file is C code, not C++ code, and it's Windows-only, so
the choice of number to string function is more limited. Using itoa()
directly is frowned upon by MSVC with warnings, so I used itoa_s() to
shut it up.

Fixing your compile error would be extremely trivial, we just need a way
of selecting itoa() vs itoa_s().

I'd even accept #ifdef __MINGW_W64__ or whatever its macro is.
