+       Use msvcrt aware primitives for creation/termination of Win32 threads.
+       * lib/glthread/thread.c: Include <process.h>.
+       (glthread_create_func): Use _beginthreadex instead of CreateThread.
+       (wrapper_func): Update signature.
+       (gl_thread_exit_func): Use _endthreadex instead of EndThread.
