Doing nothing is *much* easier than changing the path. More importantly this covers the usual situation where there is one and only one version of R installed, and it can be found via the registry. Also, because when you install R is sets the registry by default (you can tell it not to), this typically means the last installed R is the default. In normal use, this means the latest version of R.

With that installed via cygwin doing "R CMD config --cppflags" and related calls works fine. I sent some follow up emails about the next problems (using either the MS compiler or mingw32) on 14 April.
