Fixed bug 3811 - change HAVE_COPYSIGN to HAVE__COPYSIGN in SDL_config_windows.h Ozkan Sezer The patch below changes HAVE_COPYSIGN macro in SDL_config_windows.h to HAVE__COPYSIGN, so that _copysign() can be used in SDL_stdlib.h which is available in many more windows-targeting toolchains such as MinGW, MSVC >= 6, etc, and not just MSVC >= 2013. SDL_stdlib.c already has a specific check for HAVE__COPYSIGN, so I believe this is reasonable.
