The forward declaration of
extern void _mm_pause()leads to a compilation failure on GCC on Windows. The error message says that the forward declaration conflicts with the declaration in<xmmintrin.h>because only the latter isextern "C".The function is not called on GCC because of a preprocessor conditional. Guard the forward declaration with the same conditional.
