#229: HAVE_SSE2 Undefined on swscale
  Reporter:  kyl416      |      Owner:  michael

 When compiling with the latest git I get the following warning when I get
 to libswscale/rgb2rgb.o

 CC      libswscale/rgb2rgb.o
 libswscale/rgb2rgb.c: In function ‘sws_rgb2rgb_init’:
 libswscale/rgb2rgb.c:202:5: warning: "HAVE_SSE2" is not defined

 If I edit the config.h file to say "#define HAVE_SSE2 1" it goes away.

 Either configure needs to be updated to detect SSE2 capabilites, or
 swscale needs to be updated to rely on something else for the code that
 has the SSE2 check.
