I wonder if it wouldn't make sense to split out the mingw-only parts
of path.cc entirely.  I had a quick view into the file and it turns
out that of the almost 1000 lines in this file, only about 100 lines
are used by mount.  All the rest is only used by mingw code, i. e.,
cygcheck and strace.

That's obviously not part of this patch, but something we should keep
in mind for a later cleanup.
