According to the getopt documentation, if "W;" is part of optstring, then '-W
foo' should behave like '--foo'. But if "foo" uses an optional_argument, this
is not the case, since optarg is not NULL when using -W.
The passwd.adjunct.byname table will not be used to fill in password fields
in the passwd.byname replies. Instead it is used to synthesize the
shadow.byname table, should it be missing. This is a useful mode in some
installations involving Solaris.
The getdents64 syscall adds on 32-but platforms padding which isn't needed
and not included in the userlevel data structure definition. We have to
avoid copying those padding bytes in the readdir64_r function.
Like the real header, the libc-internal wrapper for wchar.h needs to
undefine the macros so that if the header was already included before
the macros don't stay defined and cause problems later.
When doing i686-unknown-linux-gnu build configured with --enable-kernel=2.6.24,
there are several warnings like this:
../sysdeps/unix/sysv/linux/i386/fcntl.c:36:12: warning: ‘miss_F_GETOWN_EX’ defined but not used
It's already so marked in dl-sysdep.c. Failure to so mark
in the header file leads the compiler to believe that the
variable should be addressable via the .sdata section.

GCC 4.5 warns about "extern void _end; &end;".
Use char[] instead, as that also doesn't fall foul
of a target's .sdata optimizations.

When not using gethostbyname4 methods we immediately aborted the loop
over the nss modules on the first successful lookup. While this is
almost always what is wanted the nsswitch.conf file allows to select
something different.
