Oops! The '.c' extension should be recognized for C files!

Answering your specific question, 'type.register-suffixes' is the right way. 
It just should not be local. OTOH, imagine builtin.jam will contain:

type.register C : c ;
type.register CPP : cpp cxx ;

You'd need to *change* the type associated with specific suffix. Probably, 
'register-suffixes' rule can take a third parameter, telling if it should 
silently change types, instead of issuing an error.
