Fixed linux gcc compilation errors

I'd prefer to see an #ifdef at the top and define the different platform calls once up there, rather than surrounding each call with the check.

Something more like this:

#ifdef _WIN32
  #define STRCOPY(dest, size, src) strcpy_s(dest, size, src)
#else
  #define STRCOPY(dest, size, src) strcpy(dest, src)
#endif
