Re: [boost] boost.python problem with "double real" in python header file

Magne,

This is a very strange looking bug.
FWIW, gcc 2.95.4 is not an official GCC release, and it's not supported...
though I have no reason to think that's the problem.

Is it possible that you have a global-scope declaration:

    typedef <whatever> real;

somewhere else in that translation unit?
