FWIW here's the condition for NetBSD when to include the declarations
in unistd.h
/*
* IEEE Std 1003.2-92, adopted in X/Open Portability Guide
* Issue 4 and later
*/
#if (_POSIX_C_SOURCE - 0) >= 2 || defined(_XOPEN_SOURCE) || \
defined(_NETBSD_SOURCE)
int getopt(int, char * const [], const char *);
extern char *optarg; /* getopt(3) external variables */
extern int opterr;
extern int optind;
extern int optopt;
#endif
So it looks like you'll have to define _POSIX_C_SOURCE=2 or
_XOPEN_SOURCE to get the defines.
