25 | /* System headers (e.g. stdio.h, stdlib.h, unistd.h) sometimes |
| 26 | indirectly include getopt.h. Our -I flags will cause gcc's gnu | |
| 27 | getopt.h to be included, not the platform's copy. In the default | |
| 28 | case, gnu getopt.h will provide us with a no-argument prototype | |
| 29 | which will generate -Wstrict-prototypes warnings. None of the | |
| 30 | target files actually use getopt, so it is safe to tell gnu | |
| 31 | getopt.h we never need this prototype. */ | |
