Actually, it didn't -- but I patched it to do so now.

We should think a bit about whether or not Cygwin should conform to the
/proc/…/stat definition of Linux with it's peculiar bit allotment for
the major/minor device numbers, in which case I'll have to change to a
versioned #ifdef (I don't particularly want to use a runtime version
check).

I still don't know where the bug is in the current package, as just
building the current version (without my patch that removes the function
that uses /proc/ctty) also works correctly.
