[Pyrex] Once more, what's wrong here

[Simon Burton]

This is what i get:

arrow:~/home/python/pyrex/sandpit$ pyrexc becker.pyx 
arrow:~/home/python/pyrex/sandpit$ gcc -I. -I/usr/include/python2.2 -g  -c becker.c
becker.c:62: field `__pyx_base' has incomplete type
becker.c:64: confused by earlier errors, bailing out

Are there other examples of this inheritance technique you are trying?
BTW It looks interesting (your code)..

Simon.
