imac:Desktop keith$ cat > conditionalvoid.c
extern void foo();
extern void bar();
void baz(int c) {
  c ? foo() : bar();
imac:Desktop keith$ gcc -fsyntax-only -Wall -Wextra conditionalvoid.c
imac:Desktop keith$ clang -fsyntax-only conditionalvoid.c
conditionalvoid.c:4:3: warning: expression result unused
  c ? foo() : bar();
1 diagnostic generated.

( ?: on void is perfectly legal according to C99 6.5.15 )
