[R] How to install RMySQL package in R 2.5 in Windows OS?

I can confirm problems with the current mysql 5.0.41: I get

> library(RMySQL)
Loading required package: DBI
Error in dyn.load(x, as.logical(local), as.logical(now)) :
         unable to load shared library 
'd:/R/library/RMySQL/libs/RMySQL.dll':
   LoadLibrary failure:  Invalid access to memory location.

I do have a successful build with 5.0.21 (the version I have been testing 
RODBC against), and have put that on my repository so it will 
automatically be available to Windows users.

The mysql 5.0.41 problem occurs equally with that pre-built RMySQL binary 
and with a build from the sources.

My Linux box is running 5.0.27, and RMySQL works there.
