   In the following short program I have a line which is never reached. gcc
rightly omits the line from the .s file, but does not print a warning that
it is omitting some code, even with -Wall -pedantic.

/* Demonstrate a problem in gcc. Note that printf("two\n") will never be
 * reached.
 */
#include <stdio.h>

void main(void) {
  int i;

  for (i = 1; i < 10; i++) {
    printf("i = %d\n", i);
    continue;
    printf("two\n");
  }
  printf("three\n");
}

                                                       scott
