Yes, I avoided the term namespace since there is no meaning like that in 
C as I assume you all know well. Obviously calling "internal" functions 
stuff like min or max is a disaster waiting to happen. On the other hand 
it is ironic that std's set was picked up, but that can be easily fixed 
for C++ code, but not C code. Given that gmax from gsl and pari collided 
lead me to the conclusion you also reached above.

I don't know, but I assume you mean this in the context of Cython.
