[Rd] 64 bit R for Windows

[Milton Lopez]

I appreciate the update. We will consider using Linux, which leads me to
one more question: what is the maximum RAM that R can use on each
platform (Linux and Windows)?

Thanks again for your prompt responses.

An additional factor is that MinGW will almost certainly follow the MS
idea that long's are 4 bytes even under Win64, unlike what every other
64-bit OS does.  It will take a fair bit of time and someonw with the
motivation to do so to sort out the consequences (which may not be
very great but even establishing that may be non-trivial).
