cygwin 1.7: why there is a directory E/cygwin/dev in the tree of cygwin ?

No, it was a hack picked up from Igor that forces cygpath into a drive
letter resolution using an arbitrary drive letter (c:, for lack of
anything better), then undoes the hack to get back at the real path
name.  But while I know it worked for cygwin 1.5, it is highly possible
that changes in cygwin 1.7 have rendered the hack bit-rotted.  I may
need to do a new release of bash that is guaranteed to better work with
installations into non-C: drives.

Thanks for the heads-up.
