error in atlas_prefetch.h

[R Clint Whaley <rwhaley@cs.utk.edu>]

Guys,

I'll be out of e-mail contact for a week or two.  In the meantime, a user
has pointed out the last developer release had a bug in
   ATLAS/include/atlas_prefetch.h:
Under the 3DNow options, change
   prefetchtw
to
  prefetchw

Cheers,
Clint
