With gcc 2.7.0, the following program incorrectly causes gcc to emit a
warning message when compiled with "gcc -c test.c".

int f(void);
void g() {
    const char * p;
    p = 0;
    p = ("", 0);
    p = 1 ? "" : 0;
    p = 1 ? (123, "") : (123, 0);
    p = 1 ? (f(), "") : (f(), 0);   /* incorrect warning here */
}
