 You need to read the documentation to discover that maybe you should
be using the right tools. Namely MinGW and not Cygwin. Unless you've
managed to compile the whole of R using cygwin of course...

 I hope having identical responses to mailing list messages and SO
questions isn't as annoying as seeing identical questions posted to
each is to everyone on the list...
