The system is the LFS 6.1.1 LiveCD (around 3 year old). The C library is
glibc and it is at least that old, too.  With the latest version of this
system shadow 4.1.2.2 compiles.

Yes, the system has man pages for getpwent and for getpwuid, but neither of
them mentions any macro.

First, neither <unistd.h>, nor <sys/types.h> is included in lib/pwio.h.
Second, including them in any order (before pwd.h) fixes the above error.
Including just <sys/types.h> also works, but including only <unistd.h> does
not.

Later on, the same error occured during the compilation of xgetgrnam.c, and
I included <sys/types.h> in lib/groupio.h, too.  After these two changes
shadow 4.1.2.2 was compiled.

Thanks for your reply,
