[racket] fixnum on a 64 bit processor

Thanks very much.
I'll try to download the 64 bit version as soon as it is available.
BTW, I almost always use the most recent build (full racket) From time to
time there may be a bug, but in general the nightly builds are surprisingly
stable for my way of using Racket. I am not afraid of non backward
compatible changes. With a set of my own testing modules it is very easy to
find where to adapt older code of my own (for a major revision, may be 10 to
at most 100 corrections on an estimated total of 50000 lines of code.
Possibly because I only use a small subset of all that Racket has to offer)
Thanks again, Jos

If you've installed the released x86 binary, then that's a 32-bit
build, which means that it works the same as it did anywhere else.
You need to use a 64-bit build to get the bigger word sizes.  We
started to make those builds shortly after the last release, so you
can try to install Windows 64-bit from the nightly builds page:
