  _mcount() is declared as returning an int, but in reality, it always
returns void as shown by those GCC errors:

  cygmon-gmon.c: In function 'monstartup':
  cygmon-gmon.c:142:7: error: 'return' with no value, in function returning non-void [-Wreturn-mismatch]
    142 |       return;
        |       ^~~~~~

Change monstartup()'s return type from int to void.
