Yes, it is indeed the case that your question is not specific to Octave. It
is more about the change (probably) from gcc 2.95 (say) to gcc 3.x.
Qualifying string to be from the std namespace (std::string) should solve
most of your problems.

There is also a c_str() method in std::string which may do some of what you
want with the string from Octave:

    std::string fn = args(0).string_value();
    char * s = fn.c_str();

HTH,
