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