[R] Compiling C codes in Windows

[Tong Wang]

Thank you all for the help . It seems I only need to change the back slash to forward slash to get things work .

As to using Cygwin as the shell, I couldn't find an instruction dedicated to Cygwin, should I just follow the " Installing 
R under Unix-alikes " ?  Is there an easier way, like making use of the installed binaries.

I will post future questions to R-devel.  

Thanks again.
