I'm not sure about the other members here, but I've been trying to use the MISRA conventions. I also somehow stumbled upon a declassified document that goes over the C++ language and style rules used for the JSF electronics, but that's another story.
As far as I know, the Codewarrior compiler is happy so long as you have ISO 9899:1990. Versions after 6 or so support 9899:1999 I think.
