If %% is used in printf formats without any actual format requiring
substitution being used, gcc still does not perform the optimization.
#include <stdio.h>
int
main (void)
{
printf ("hello %%%%!\n");
return 0;
}
This code is compiled to call printf even though it should lead to code calling
puts with the string containing "hello %%!".
