Actually, I'm talking about the general SWIG docs -- that have nothing 
to do with numpy at all. They've got you calling gcc on the command 
line, which I haven't done for years!

But while we're on the topic, I started this be looking at the swig 
examples that come with numpy. It would be really great if there was a 
complete, very simple, sample or two complete with c code, *.i files, 
and setup.py. There are the tests, which built and ran fine for me, but 
that's a bit of a complicated mess.

Anyway, I'm working on some simple samples -- I'll contribute them when 
I get them working!

OT:
The struggle at the moment is building a C++ extension -- if I use 
straight C, a trivial sample works, if I call the file *.cpp, swig it 
with -c++, I get a *_wrap.cxx file that won't build. Do I have to do 
something different in the setup.py?
