[racket] fixnum on a 64 bit processor

Thanks very much. I just downloaded the latest nightly build of the full
windows x64 version and my fixnums indeed go up to and including 62 bits. I
keep being amazed about how quick PLT responds to customer requests and how
rapidly Racket is develloping further ad further. On the dev list, which I
read but as a non-develloper do not post to, I can see how carefull
decisions are made. GREAT! (; sorry about shouting ;)

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:
