/*
* FIXME: dangerous TRAP here!
*
* all of these functions get compiled into BaS with "normal" GCC integers (32 bit). However, since they will be called
* from code compiled with -mshort, integers must be declared uint32_t for those compilation units to adhere
* to "normal" GCC calling conventions.
*
* This is ugly and slow (all stack frames from -mshort compiled code need to be rearranged for "normal"
* calling conventions), but that's the way it currently is...
