Actually, that's not the case and is irrelevant as Lee demon-
strates in https://cygwin.com/ml/cygwin/2016-12/msg00220.html.

Comparing the output from
Windows: C:/>path
and
cygwin/bash: $ cmd /c path
shows only new paths added to support Cygwin.

I'm on Microsoft Windows 7 Enterprise Edition, 64-bit Service Pack 1 (build 7601)

FWIW, output from "cygcheck -svr" attached.
