xlc versions 1.1.8.9, 1.1.8.11, 1.1.8.12, and 1.2.0.0 all generate an
incorrect error message for this code. Version 1.1.8.0 does not.
typedef void (*proc3)(int, int, int);
typedef void (*proc2)(int, int);
f(proc2 fnp){(*(proc3)fnp)(1,2,3);}
It appears that xlc is checking the argument list against the type of
fnp, not the type of the casted expression, because it says
"unexpected argument" with the arrow pointing at the third argument.
