  11     # gcc lameness is that, in order to compile SSE2 intrinsics code, it

  15     # code must be compiled *without* -msse2.  The gyp lameness is that it
  16     # does not allow file-specific CFLAGS, so we must create this extra
  17     # target for those files to be compiled with -msse2.

  19     # This is actually only a problem on 32-bit Linux (all Intel Macs have

  21     # SSE2 from instrinsics, which generating plain ol' 386 for everything
