Transitions appearing in a C-language statemap end up in a list of transition functions (delcared static) that are subsequently #define-macro'd to state-specific substitutes.
If a transition only appears in the Default state, that transition function's xyzMap_DefaultState_transitionName macro gets #undef'd and replaced by another static function, xyzMap_DefaultState_transitionName(...) lower down in the generated .c file.
This creates an unused function warning, similar to ticket #224, even after the transition is called from client code. Many organizations standardize on running gcc with -Wall -Werror, requiring file-wise workarounds to disable this warning.
