not is C++ operator:

  bool operator not() const {
    return PyObject_Not(_obj) == 1;
  };

works in gcc 3.0 and 3.1 but not in gcc 2.95. The following works in all
versions of gcc:

#if defined(__GNUC__) && __GNUC__ < 3
  bool not() const {
#else
  bool operator not() const {
#endif
    return PyObject_Not(_obj) == 1;
  };

I don't know which one road works for other C++ compilers but my guess
would be the #else part provided that these compilers follow C++ standard
closely.
