so many #ifdefs in:

# if defined(_POSIX_REENTRANT_FUNCTIONS) || !defined(SVR4) || defined(Lynx)

src/include/pwd.h

int		 getpwnam_r(const char *, struct passwd *, char *, size_t,
				struct passwd **);

#define _XGetpwnam(u,p) の引数は、最後の場合を除いて次の通り。

	openMotif-2.2.3/lib/Xm/Xmos.c	src/include/pwd.h
1	(u)	const char *
2	&(p).pws	struct passwd *
3	(p).pwbuf	char *
4	sizeof((p).pwbuf)) == -1) ? NULL : &(p).pws)	size_t
5		struct passwd **

しかし最後のを選んでいれば、5 つある ?
