[Cbc] Fix for uninitialized member variable _noNames in CoinModel

[Ted Ralphs]

Hi Victor,

What version are you using? This seems to be fixed already in trunk.

The version number you updated is from an older versioning scheme. It would
be nice to make it match the real CBC version number, but this is not
actually a "number" and has hence been added to the solver name (see
below). Do you happen to know if the version number you updated is
necessary and if not, will replacing it with a zero suppress its use?

static Option_Info Oinfo = {
    const_cast<char*>("cbc"),
    const_cast<char*>("CBC " CBC_VERSION),
    const_cast<char*>("cbc_options"),
    keywds,
    nkeywds,
    0,
    0,
    0,
    decodePhrase,
    0,
    0,
    0,
    20070606
};

Ted
