Well I don't know what the dpANS says about this, but I had problems
with QuickC not recognising that I had declared (prototyped) several
functions.  Eventually, I realised this behaviour was only happening
on functions with no params, then by changing for example 

	int main(void)  { ... }
to
	int main() { ... }

it worked fine.  Maybe its a bug in QuickC, but I've seen examples of
writing prototyped functions, and in every case the prototype takes
void, and the definition takes empty parentheses.
