Huh?  Do the copy, then give a failure message?  No.  A failure message
should only occur if the copy failed.

Did you mean "continue to fail, but make the failure message more
friendly?"  If so:
Patches to coreutils welcome.  But be aware that this error message uses
the equivalent of perror(), where EEXIST would not have quite that
wording.  In other words, such a patch would be pretty invasive, to
recognize the exact errno value that cygwin1.dll returns in this
particular failure-to-create case, then massaging just that error case
into your desired message, so I probably won't be writing the patch any
time soon (I've got higher-priority things on my plate at the moment).

Or did you mean "change it to succeed, in spite of the naming conflict",
in which case there is no failure message and nothing to patch in coreutils.
