If code can be compiled on a wide range of platforms then that means
that it's much easier to get build coverage of the code.  This is
helpful for anyone doing any kind of cross tree updates - things like
updating APIs for example.  The fewer configurations they have to touch
to get everything built the easier it is for them.
