ecosconfig should not be invoking the "mount" tool. Please be very clear
as to what you observe, with what version of the tool and when. Do you
see the above mount usage message when invoking "ecosconfig tree" or
some time later? Is this with your own build of ecosconfig which you
were able to create by adding "#define NOMINMAX"?

I expect there's some minor incompatibility with the Cygwin 1.7.x mount
scheme that needs sorting out.

The pre-built ecosconfig binary from the eCos 3.0 release should work
with almost any Linux distribution which provides libstdc++ v3
(/usr/lib/libstdc++.so.5). Ref:
