probably I am missing something obvious, but should not

/usr/include/sys/cdefs.h

be included in some way in
/usr/include/pwd.h

to make working the

     #if __XSI_VISIBLE >= 500
     struct passwd   *getpwent (void);
     void             setpwent (void);
     void             endpwent (void);
     #endif

?

Marco
