[Openvrml-develop] OpenVRMLcore Codewarrior project errors

[John R. <ric...@sp...>]

Hello,

I am having problems getting the OpenVRMLcore.mcp project to compile under
Codwarrior 6.

First some results of queries to the CW list and then some snippet's from
the warnings for CW savy people. Perhaps just a case of some newbie type
questions about C++ since my C++ is rusty......

Here are some of the questions I posed to the Codewarrior list and a response
from the metrowerks list guru.
