[R] R and ATLAS on Windows

[Prof Brian Ripley]

A while ago there was some request for supporting the ATLAS BLAS libraries
on Windows.  I have finally succeeded in building the ATLAS libraries, and
made the necessary changes to the Makefiles.  This will be available
in R-patched as from tomorrow's snapshot: see src/gnuwin32/INSTALL for
how to use it.

You will need to build an ATLAS library for your precise chip.  This can
be a frustrating experience.  On my laptop (mobile PII) it took about an
hour.  On my desktop (dual 1GHz PIII) the first attempt failed after 2
hours and the second succeeded after four.  Because of the extreme chip
dependence, there is no way that we distribute ATLAS-equipped binaries.
