I assume that you have made ATLAS compile on Windows? I failed with the
current version ....
You will need to do a fair bit of work. BLAS uses src/appl/blas.f. Remove
that and re-make in src/appl, then link lapack.so and R.dll against the
ATLAS dll you made.

src/gnuwin32/bitmap/INSTALL tells you what to do, indeed the options you
need to compile them. You don't need to move them from there.

That's recent: it worked last week, as I checked all the links in
R-1.3.0 before release.
It comes with VisualStudio, for example. Looks like it is now part of
.NET beta SDK.
I'll try to find out if I have permission to put it up.

(My tests were much less spectacular. After running R with ATLAS on both
Linux and Solaris I stopped, as I rarely saw more than a few percent gain
on my real tasks. Your mileage may vary.)

If you do succeed, contribute back what you did please.
