I went through webrev.05 and the new Platform enum looks reasonable to 
me (and thanks for the rename too). I checked the os.name mapping and it 
looks right. Whether it's Error or InternalError for an unrecognized 
platform probably doesn't matter here.

If Roger is okay with this version then I think we should get this merge 
done and look at other refactoring with a later change. Also if 
src/solaris is renamed (and I know many of want do this) then it's 
another opportunity to come back to the topic too.
