I would highly suggest looking at google guidelines.
http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml
They are aimed at taking some of the landlines out of c++ and give pros and
cons for each argument.
There are many places in the gcc source where we are already doing C++ things.
I would think those would be the best places to start.
Adding classes (especially with inheritance) should not be a development
decision but instead a design decision. To really move towards C++ we really
need to develop a model of what we would like the code to look like.
