[Rd] Problem with tuned Rblas from CRAN with R-2.4.0

I just ran the example on a Win2000/P4 BLAS DLL system.  It works fine on
2.4.1 beta (2006-12-10 r40146) as well as 2.5.0 Under development
(unstable) (2006-12-10 r40146).

I have had the same DLL file for a couple of years now (downloaded from the
Wisconsin CRAN if I remember correctly) but occasionally I check the file
sizes between the one available on CRAN and the one I have and the size (in
bytes) seems to stay the same.

I just looked into the one for P4 and it does export zdrot_ and works
for me. Is your one from CRAN master?

I checked the changes file and saw that for R-2.4.0 the Rblas.dll would
have to be recompiled, but also that the contributed binaries on CRAN had
been updated.  However, I couldn’t find any Rblas binaries with a date
after 2005.  Any suggestions on where to find an Rblas binary for WinXP and
P4 chip, or do I need to try to compile one on my own?
