The problem is the global variables in a few files (e.g. V128 in
recon_mmx.c), I'm pretty sure.

Unfortunately, I don't know what the solution is. Possibly loading the
constants into local variables (in the surrounding C code) and only
using the locals would be a workable solution; there might be better
