Build problem: rabin_dedup.c:908 -- unknown type name ‘__m128i’

Hi there,

pcompress looks amazing! Thanks for all your hard work.

I'm having a problem building it on Arch, however.

This happens:

Any ideas?

There was a bug in not properly handling non-SSE4 CPUs. Can you please checkout the latest git and rebuild.

You bet I can!

SUCCESS! Thanks!
