Likewise but I'll chop some dead wood too.

Ok. It simply is harder because of the need for the env vars.

Odd. I have seen (and suppressed) the recent Cygwin noise.

I wonder if there is something in your path that messes this up.  Recall the
dire warning in the R-windows FAQ to make sure that Rtools et al come first.

Not sure. "Works for me and other" as they say.

Sounds good.  In general, this works.  Windows is by far the most tedious
platform but it should work even here.
