Yes, currently windows version can't load gems.

For a month ago, I wrote a patch 7.3.058 . But the patch have a
problem.
One of calling function 'Init_prelude' is not compatible for all
platforms.
Then I wrote 7.3.067 . 'Init_prelude' include the part of loading
gems.
However, I have another patch for fixing this problem.

https://gist.github.com/751492

This patch fix the problem. vim will be able to load gems completely.
But ruby on windows have a bug that show warning message while loading
gems.

http://redmine.ruby-lang.org/issues/show/2998

Thus, I'm hesitating whether to suggest this patch.

Bram, How do you think?
