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.
