That is a reasonable suggestion if i were willing to mess around with
Windows long enough to install the tools for building packages, etc.
However, my patience for working on Windows runs out after about 5
minutes and I think it will be easier on computers and people near me
if I just create a version of lme4a that will compile against

You see I work on Ubuntu or Debian systems all the time and there is
this marvelous guy named Dirk who makes it so simple to install the
packages and the build environment etc. there that i am rather
spoiled. :-)
