You presumably meant "gint8", that being what you used in the commit.
int8_t is a C99 datatype; older versions of various UN*Xes might not support
it, and, even on those that do, you might have to include <stdint.h>. Given
that older versions might not support it, and might not have <stdint.h>, it's
probably best not to use it.
According to
http://blogs.msdn.com/b/vcblog/archive/2013/07/19/c99-library-support-in-visual-studio-2013.aspx
VS 2013 adds <stdint.h>; I don't know whether that means you need MSVC 2013 or
later to build ws_mempbrk_sse42.c. I also don't know whether, with your
change, ws_mempbrk_sse42.c still needs to include <stdint.h> on Windows.
