Please read the mailing list archives. I think this is a bug introduced 
by a Microsoft Windows XP patch some time (i.e. several months) ago. 
"R-1.9.1 patched" has a workaround.

Well, you have to re-install packages, because some changes in R-2.0.0 
make it necessary.

Please take the sources of "GLMM", read .../src/gnuwin32/readme.packages 
and follow the advice how to compile packages yourself.
