I saw your announcement on the CCL, but did not have time to look at
updating chemfp yet.  Debian (an thus the chemfp packages, as it is
present in testing) is currently frozen in preparation for the next
release, but I started updating some packages recently.

I am now filing this as a wishlist bug to keep track of it.

OpenMP should be doable.

If the SSSE3 support is not runtime-detected, we will have to configure
it out on ia32, as the baseline is currently a regular i686 CPU (without
SSE) I believe.

On amd64 I am less sure, but I think there are some x86-64 CPUs around
which do not support it.  I assume the code will result in a SIGILL on
those CPUs?  That might also be a problem.
