Hey Thanks!  I'm glad to know what was happening here.

For now I'll leave it off so that it doesn't crop up as a problem on
other platforms -- it isn't really that critical.  Once we get most of
the other stuff ironed out, we can look at adding it back in.
Currently, there aren't any ifdefs.  That probably won't last long, but
I'm loath to add them right now. :-)

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.
