The include of <getopt.h> in <unistd.h> is within #ifdef __USE_POSIX2. I
think <unistd.h> assumes IEEE Std 1003.1 by default, which presumably
doesn't include getopt(). See the top of /usr/include/features.h for
more; it looks like you could define _POSIX_C_SOURCE to 2 in addition to
-ansi, for example.
