I got around this by putting copies of (e)mmintrin.h in the local 
directory and changing b0..b3 to different names.
One can get evaluation copies of icc that work for a month. I'm curious 
to see if there's a considerable speedup due to the different compiler ;-)


I also tried to compile xdvipdfmx from the SVN sources. During 
./configure I get
   checking size of char... configure: error: cannot compute sizeof 
(char), 77

This happens with both gcc and icc.
