It's a mount. Try "man mount" or read about mounts in the User's Guide
(<http://cygwin.com/cygwin-ug-net/using.html#mount-table>).
Which also means that /usr/bin != c:\cygwin\usr\bin, with all the obvious
consequences.

Umm, weird. Sufficiently weird that we need to know more about your
installation to be able to help. Please read and follow the Cygwin
problem reporting guidelines at <http://cygwin.com/problems.html>,
particularly the part about *attaching* the output of "cygcheck -svr".

The above also implies that your rc files may contain weirdness. Please
also attach the contents of .bashrc and .bash_profile in your home
directory.
