Click the 'install now' button at cygwin.org, and when the selection box 
appears in the install process, also select gcc.  There is a _lot_ of stuff
available for cygwin that the default install ignores.

That said, it won't help you for R as you cannot build R under Cygwin. The R
Extensions and R Admin manuals for details -- you'd want MinGW, a "cousin" of
Cygwin, on the PC.
