Hello!
At ZNC we have an own string class CString, which is inherited from
std::string.
The goal is to use it as a just string in target languages.
How to do that properly?
When I was writing modperl and modpython ZNC modules, I used an approach
described at
http://old.nabble.com/Forward-declaration-error--td24064356.html
Used "swig -E" on std_string.i, got a long file as a result, cleaned it
up and changed all occurences of std::string to CString.
It worked fine before SWIG 2.0.5, but in 2.0.5 it started to give errors
while generating sources for modpython:

Sending copy of the letter to 672...@bugs.debian.org
Also there is related issue #174 on github/znc.
I can't replicate this bug with 2.0.6, you are going to have to provide
a test case. swig-2.0.5 introduced a regression which was fixed in 2.0.7
- incorrect typemaps for templates were being used in conjunction with
typedef. Please try 2.0.7 and report back if fixed.
