Your proposal appears to work better than expected:
On a 64-bit machine, it reported
64 when R64 was launched
32 when R62 was launched
On a 32-bit machine, it reported 32.
The underlying issue for me is that I am calling c code — I want t
I believe that b. is .Machine$sizeof.pointer*8.
I am not aware of a method to figure out the difficult part of a.: whether a 32
bit R is running on 64 bit Windows. I'd expect that you have to ask the OS
somehow. Google coughs up one or two interesting pointers.

Colleagues,
If I am setting up code for others and I dont know their configuration, what
is the simplest way to find out the following within R:
a. is the system 32- or 64-bit?
b. if the system is 64-bit, is R 32- or 64-bit?
