Just for information, can someone tell me how Debian (which has a `i386'
port) can possibly use ATLAS properly?  I find that there are major
performance differences between versions of ATLAS tuned on different
Pentium II chips (PII-450 vs mobile PII-366, for example) so that a large
part of the performance gain goes if they are switched.

Reason for question: I might put out an ATLAS-equipped Windows version of R
if I had any idea how to produce a `i386' version of ATLAS.
