Besides putting a potential ifdef in neuralnetsse.c (like below) I discovered one other glitch. If you enable SSE2 (via —enable-sse=sse2) there appears to be a bug in the configure.in where the Makefiles are generated with –msse instead of –msse2. My opinion is this. Configure.in logic should simply be modified to reuse SSE_FLAGS so that if SSE2 is being used SSE_FLAGS should be –msse2, and if its just SSE then it should be –msse  (and blank otherwise) . I believe SSE2_CFLAGS is not needed.

#ifdef USE_SSE2
#include <emmintrin.h>
#include <xmmintrin.h>

I have put away these changes. If there are any issues please feel free to fix them.

My fix would be to use an ifdef to include emmintrin.h only if USE_SSE2 is defined, and include xmmintrin.h
