Trying to figure out what is wrong in a colleague's Cygwin setup

[David Karr]

Ok, well, we managed to resolve this, but I don't understand why what we
did would fix this.

In system environment variables in Windows, they added "c:\cygwin64\bin" to
the end of the PATH. That fixes the problem. That just doesn't make any
sense to me. In a Cygwin shell, "/usr/bin" is in the PATH, which is the
same as "c:\cygwin64\bin".
