It's not a crazy warning. I saw warnings from the Catalyst builds after
updating `megas`. The one in vtkObjectFactory is a false positive, but
rewriting it to use `std::string` instead of `strncat` just makes the
code easier to read anyways. Errors in pv-forward.c.in were real and
(since it is C), `snprintf` is the better solution there.

Basically, `strncat` is a function that is really easy to screw up. We
really shouldn't use it in C code and certainly not at all in C++ code.
