is there a library with a function to mangle names?

[Pavel]

Hi,

I would like to mangle C++ names using same algorithm as g++ (to then 
dynamically load them from shared libraries). I only need to support g++ 
versions from 4 on. Is there a ready library that I could use or should I just 
borrow the logic from g++ or c++filt source code or none of the above?

Thanks,
Pavel
