To mark this as SOLVED:

I have got this working by including a simple clause in the function called on hook.

(if (string= "c-mode" major-mode)
  (progn
    (c++-mode))) ;; Switch C mode to C++ mode (because we use .h!)

Now things just work. I also forgot failed to realise how useful it is to switch to C++-mode when looking at a C++ .h file: the emacs colouring is all correct when in C++-mode, eg:

static void MyStatFunc(); 

the keyword were not being read correctly, so void would be the colour of the method name etc.

All good now with this hack, but still wondering why I needed to do M-x c-mode again in the first place to get things to run.
