How so? If they need the win32-mswin version then it is easier to
detect the platform in code from Config::CONFIG than it is for the
user to have to remember (or guess) if they are using ruby built with
the mswin, cygwin or msys compiler (or whatever they are). After
all, this is what computers are for.

New operating systems don't pop up every day. I think we can release
a new version of rubygems (or a separate platforms gem, like the
sources gem) easily enough.
Having written a program to go through the specifications of all the
current gems, there's a lot of crap in there. Allowing users to
arbitrarily specify something will result in no less than 3 strings
that mean the same thing with at least one string specifying two
