[Pyrex] [Cython-dev] 'cdef public' functions with a C++ compiler

[Robert Bradshaw]

It looks like this is a bug, and since we haven't done anything with  
this part of the code (as far as I know) it would be a bug in Pyrex  
too. However, we have several C++ files that compile fine with g++,  
so more details would be needed to reproduce this.
