I was confused. I see the only version of the library shipped is built
with pthreads. I think there should be serial, pthreads, and OpenMP
versions, as for Fedora. It may also be useful to provide the 64-bit
integer versions, like Fedora; that's useful for at least a flagship
chemistry program.
I also remembered the problems with 0.2.20. I'll send a patch for the
wrong cache size used on some x86_64 when I get a chance.
