This is the only minor qualm I have with this patch.  It would be nice
to have the mingw sources and .o files in the mingw subdir.  It would
simply be a bit cleaner.  The files shared between cygwin and mingw
(that's only path.cc, I think) could be handled by an include, i. e.

  utils/

    path.cc (full implementation)

  utils/mingw/

    path.cc:

      #include "../path.cc"

However, this isn't a showstopper, feel free to push what you're comfortable
with.

Still, wWhat do you think?  Any problem to move the mingw stuff to the
mingw subdir entirely?


Thanks,
