Guys,

It's been a bit in coming, but I have just released 3.7.35.  Here's the 
ChangeLog entry:

ATLAS 3.7.35 released 07/26/07, changes from 3.7.34:
   * Changed it so pthread calls assert zero return value (debugging aid)
   * Improved threaded GEMM performance for cases where two dim < NB
   * Increased default MaxMalloc to 64MB
   * Improved Windows support:
     - Added support for building Windows ATLAS with Intel's ifort
     - Added support for building on Windows without the cygwin library
     - Added ability to get cycle accurate timer when using Windows compiler
   * Improved POWER4 & P4SSE2 arch defaults.
   * Removed duplicate symbols in Make.mmsrc messing up shared library building

The big news (if you can call it that) is that I've gotten ifort working 
on windows.  You can see details about the hoops you have to jump through
in the errata draft entry:
   http://www.cs.utsa.edu/~whaley/atlas/errata3.8.0.html#WinComp

I still do not have it working if you want to use MSVC++ or intel's C compiler
to build ATLAS itself.  However, I think you should still be able to link to
the gcc-built lib using MSVC++ or Intel C.  Does someone out there use ATLAS
on windows?  If so, let me know if you can link to the ATLAS libraries
(using the tricks in the errata) from these compilers.

Cheers,
Clint
