L.S.,

Different error report (which was the objective of Ben Wijen):

     https://cygwin.com/ml/cygwin-patches/2019-q2/msg00136.html

Now, let's play:

64-@@ cygpath -w /drv/e
E:\

64-@@ mkdir 'e:\' # creates subdirectory e: !!!!!
64-@@ rmdir 'e:\' # fails, because it refers to /drv/e
rmdir: failed to remove 'e:\': Directory not empty

64-@@ rmdir 'e:'

Yes, I should NOT use "DOS paths" ...

     https://cygwin.com/cygwin-ug-net/using.html#pathnames-win32

However, I wonder why e:\ is interpreted by mkdir as e:, and as
/drv/e (that is as e:\) by rmdir.

Any reason for this remarkable difference?

Regards,
Henri
