      The problem is caused by this bit of code in /usr/include/pwd.h:

 #if defined(_NETBSD_SOURCE)
 int              pw_gensalt(char *, size_t, const char *, const char *);
 int              pw_scan(char *, struct passwd *, int *);
 int              setpassent(int);
 int              getpwent_r(struct passwd *, char *, size_t, struct passwd **);
 const char      *user_from_uid(uid_t, int);
 int              uid_from_user(const char *, uid_t *);
 int              pwcache_userdb(int (*)(int), void (*)(void),
                                 struct passwd * (*)(const char *),
                                 struct passwd * (*)(uid_t));
 #endif

 _NETBSD_SOURCE isn't defined for compat (i.e. tools) building.
 However, several of these functions are provided by our compat
 library.  I propose the following fix:
 
 -----
 
 #if defined(_NETBSD_SOURCE)
 int              pw_gensalt(char *, size_t, const char *, const char *);
 int              setpassent(int);
 int              getpwent_r(struct passwd *, char *, size_t, struct passwd **);
 #endif
 
 #if defined(_NETBSD_SOURCE) || defined(HAVE_NBTOOL_CONFIG_H)
 int              pw_scan(char *, struct passwd *, int *);
 const char      *user_from_uid(uid_t, int);
 int              uid_from_user(const char *, uid_t *);
 int              pwcache_userdb(int (*)(int), void (*)(void),
                                 struct passwd * (*)(const char *),
                                 struct passwd * (*)(uid_t));
 #endif
 
 -----
 
 Since I'm not famailiar with how our compat library works, I would like
 somebody else to verify that this is correct.
