Keywords: return void cast

This problem occured when I ported a program to a UN*X system on which
signal handlers were "void (*func)()", instead of the usual "int (*func)()".
I used a "typedef int SHND_TYPE" in a system-dependent include file, 
which I changed to "typedef void SHND_TYPE". But then I ran in problems
with the return *action*, not the *value*:

SHND_TYPE catchit (...) {
	... some useful code ...
	return ((SNHD_TYPE) 0);
}

Maybe returning something which has been cast to void should be made
equivalent to "return;".
