This little snippet prints "true" if compiled with gcc and "not true" if
compiled with tcc.
int main (void){
printf ("%sok\n","a"=="a"?"":"not ");
return 0;
}
Note that "a"=="a" is not what it looks like. We are comparing the
address of the pointer "a" with itself. If the book I just looked at
(Banahan, et al., 1991) interprets the standard correctly, a quoted
string serves as a pointer to the first element, thus "a"=="a" should
return true.
