R for Windows is compiled using the MinGW port of gcc, and the 64 bit 
version of that compiler is not really ready for general use yet, so 
compiling for 64 bits is not completely straightforward.  Revolution 
Computing has announced on the R-devel list that they are beta testing a 
build, with some information at

http://www.revolution-computing.com/products/windows-64bit.php

The page says it is scheduled for release at the end of March, so there 
should be something available soon.

I have not been doing low level programming for a while now and therefore, the self compilation on windows would be the least preferable (and then I have to worry about how to compile any modules that I need).
