Re: g++ 3.0.1 does not compile the attached file but 2.96 does

[Andrew Pinski <pinskia at physics dot uc dot edu>]

Since gcc 3.0 is more standards compliant: list, string, cout, cerr,
and most other things included in standard headers are now in
the namespace of std, gcc 2.95.2 ignored this namespace unless
you passed it "-fhonor-std"
