I used it with 32 bits builds. I did not provide the compilation target
for 32 bits mode, but this should be quite easy to have it working.
MD5_SSE_PARA should be 2 instead of 3 because of register pressure,
juste as Freddie Witherden mentionned. But if you really want to work on
that, you should just forget 32 bits mode.

It is the Intel C Compiler. It performs a lot better than any version of
gcc/clang with this code. For some reason it performs a bit worse than
GCC for the intrinsics DES build, but I believe it is worth having it.
They just changed the name :

You can download an unlimited trial version for Linux, but you'd have to
pay for the Windows version.
