The TODO list has this item:
* get_cwd for cgywin
I've attached a patch which implements this, along with get_name.
Cygwin's /proc filesystem is similar enough to linux's that the code
could be copied from osdep-linux.c, and that's what I've done.
osdep-cygwin.c is just a copy of osdep-linux.c, just without the
setting of EVENT_NOEPOLL, since this doesn't seem to be needed on
cygwin.
