RubyGems uses platforms for two things[1].  The obvious use is selecting 
the platform for possible gems to install[2].  The other use is when 
installing command file, RubyGems will create .cmd files for all the 
programs in the gem.  I would imagine that we still need to do this for 
the JRuby version, right?  It seems to me we need to differentiate 
between JRuby on windows vs JRuby on Unix.  Perhaps the platform string 
is not the appropriate mechanizm for this.  I'm will to hear 
alternatives.

[1] That I can think of off the top of my head.
[2] Yes, the platform selection logic is currently rather weak.  We hope 
to fix this in the near future.
