getopt(3c) on  Solaris 9 (and Solaris 10) says:

  SVID3, XPG3
     #include <stdio.h>
     int getopt(int argc, char * const argv[], const char *optstring);
     extern char *optarg;
     extern int optind, opterr, optopt;

  POSIX.2, XPG4, SUS, SUSv2, SUSv3
     #include <unistd.h>
     int getopt(int argc, char * const argv[], const char *optstring);
     extern char *optarg;
     extern int optind, opterr, optopt;


So both those man pages says that the correct header varies
depending on the compilation environment.
I see that /usr/include/stdio.h and /usr/include/unistd.h
do indeed make the declaration of getopt() contingent
upon various other macros.
