Occasionally, when installing win32-specific gems, I get choices
like the following (I'll use win32-process as an example):

1. win32-process 0.5.3 (ruby)
2. win32-process 0.5.2 (ruby)
3. win32-process 0.5.1 (ruby)
4. win32-process 0.5.0 (mswin32)
5. Skip this gem
6. Cancel installation

So what does the (ruby) vs. (mswin32) tags mean?  Of course this is
for win32--it's a win32 extension.

Should I install the latest gem, or the newest mswin32 one?  Why is
there even a choice of ruby vs. mswin32?
