Sure, you're right. I was just trying to get the code to build, and  
touch it as little as possible in the process, but I'd be happy to  
see it handled better.

Sounds fine. Would you want that function to use the platform's  
strndup if available, or do you prefer to ignore it and use a local  
implementation in all cases?

I see there's copyString() in gmem.cc, which looks like a strdup  
reimplementation. The naming seems a bit illogical; why isn't it  
gstrdup? What should the version of strndup here be called, then?
