This ensures that if there is an error in the definition of the
PENDING_OUTPUT_N_BYTES expression, we'll find about it right away;
that value is used only in the rare event that close_stdout's
fclose fails with EBADF.
(__fpending): Abort if PENDING_OUTPUT_N_BYTES is negative.

Include "exitfail.h".
(openat): Remove #undef; no longer needed now that we include openat.h first.
(rpl_openat): Add comment about mode_t promotion. Simplify
code a bit by moving initializations around. Use exit_failure
rather than EXIT_FAILURE.
(O_DIRECTORY): Remove; not needed here, since "." must be
a directory. All uses removed.
(save_cwd): Use __sgi || __sun, not sun || __sun. __sun is
universal on Suns, and we also need to test for IRIX.
Revamp code to use 'if' rather than '#if'.
Avoid unnecessary comparison of cwd->desc to 0.
Include "strdup.h".
(GLIBC_VERSION): New macro.
(hard_locale): Assume setlocale exists.
Rewrite to avoid #ifdef.
Use strdup rather than malloc + strcpy.
(__getcwd.c): Don't restore errno; glibc doesn't.
[HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd
first, falling back to our code only if its results look suspicious.
Ensure that the resulting buffer is only as large as necessary.
<sys/param.h>, <time.h>; not needed to establish interface.
Include <stddef.h> instead.
(errno): Remove decl.
(HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed.
(UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME,
UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros.
