[R] Cross Compiling

[Douglas Bates]

An alternative to cross-compiling when you have a source package is to
use the Win-builder facility at win-builder.R-project.org

Thanks to Uwe for providing this facility.  I find it much, much
easier than trying to cross-compile or to set up a Windows computer
for compiling R packages.
