[Cbc] distinct or missing rownames

[Tom van der Hoeven]

using an .lp file i get the message:
----------------
### CoinLpIO::checkRowNames(): non distinct or missing row names or 
objective function name.
Now using default row names.
----------------
Soplex from the Neos server did not generate such a message.

- is there an option to get more details, like which name is used twice
