+ Sync from coreutils.
+
+ * getdate.y (relative_time): New type.
+ (RELATIVE_TIME_0): New constant.
+ (parser_control): Use relative_time instead of doing it ourselves.
+ (%union): Add new relative_time rel member.
+ (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):
+ Now typeless.
+ (relunit, relunit_snumber): Now of type rel.
+ (zone, rel, relunit, get_date): Adjust to above changes.
+
+ * getloadavg.c: Include fcntl--.h rather than fcntl.h.
+ Do not include unistd-safer.h.
+ (getloadavg): Don't call fd_safer; no longer needed
+ now that we include fcntl--.h.
+
+ * mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
+ (make_dir_parents): Treat ENOSYS like EEXIST.
+
+ Improve quality of diagnostics on restore_cwd failure.
+ * mkdir-p.h (make_dir): Remove. All uses replaced by mkdir.
+ (make_dir_parents): Last arg is now int * (for errno), not bool *.
+ * mkdir-p.c (make_dir, make_dir_parents): Likewise.
+ Rewrite "mkdir -p" algorithm to avoid the need for "stat"
+ each time through the loop. Do not diagnose restore_cwd failure;
+ that is the caller's job (and perhaps the caller does not care).
+
+ * mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
+ (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
+ If the file already exists but is not a directory, don't bother
+ to try to make its parents.
+ Close potential file descriptor leak if we can't chdir("/") (!).
+ Don't always return true if chdir($PWD) fails; return true only
+ if the requested action was done successfully (except for the
+ chdir($PWD)).
+ Don't log final directory unless we actually made it.
+ Refactor to avoid duplicate code to fix up permissions.
+ Don't attempt to fix up parent permissions if chdir($PWD) fails.
+
+ * strftime.c (my_strftime): Rewrite the previous change slightly,
+ to make it a bit faster and (I hope) clearer.
+ * strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
+ Fix bug in formats like %2N.
+
+ * verify.h: New file.

+ Sync from coreutils.
+
+ * getdate.y (get_date): Undo part of the 2005-04-04 change, so that
+ the command "date -d'2005-03-27 +1 day'" succeeds once again, even
+ when run in a time zone for which daylight savings time is in effect
+ for the starting date.
+
+ * mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
+ stop us from restricting permissions of just-created absolute-named
+ directories.
+ * mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
+ to restore initial working directory.
+ * mkdir-p.c (make_dir_parents): New parameter: different_working_dir,
+ to tell caller if/when we change the working directory and are
+ unable to return to the initial one.
+ * mkdir-p.h (make_dir_parents): Update prototype.
+ * mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
+ `return false'. This fixes a bug introduced on 2004-07-30.
+
+ * openat.c (fdopendir): Be sure to close the supplied
+ file descriptor before returning. This makes our replacement
+ implementation a little closer to Solaris's, where fdopendir
+ ties the file descriptor to the returned DIR* pointer.
+ * openat.c (unlinkat): New function.
+ * openat.h (unlinkat): Add prototype.
+ * openat-die.c (openat_save_fail): Rename from openat_save_die.
+ (openat_restore_fail): Rename from openat_restore_die.
+ * openat.c, openat.h: Reflect s/_die/_fail/ renaming.
+
+ Provide an alternative to exiting immediately upon save_cwd or
+ restore_cwd failure. Now, an application can arrange e.g.,
+ to perform a longjump in that case.
+ * openat.c: Include dirname.h.
+ Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
+ (rpl_openat, fdopendir, fstatat): Call openat_save_die
+ and openat_restore_die rather than calling error directly.
+ Don't include "error.h" or "exitfail.h"; they're no longer needed.
+
+ * openat-die.c (openat_save_die, openat_restore_die): New file.
+ * openat.h (openat_save_die, openat_restore_die): Declare and define.
+
+ * strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
+ size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
+ int utc, int nanoseconds);
+ Background:
+ date should not have to allocate a megabyte of virtual memory to
+ handle a format argument like +%1048575T. When implemented with
+ strftime, it must allocate such a buffer, use strftime to fill it
+ in, print it, then free it.
+ With fprintftime, it simply prints everything and exits.
+ With no need for memory allocation, that's one fewer way to fail.
+ * strftime.c (my_strftime): Parse the colons of %:::z *after* the
+ optional field width, not before, so we accept %9:z, not %:9z.
+ (my_strftime): Be sure to use L_('x') for literals.
+
+ * getloadavg.c, mkdir-p.c, openat.h:
+ Assume HAVE_UNISTD_H, i.e., include <unistd.h> unconditionally.
+ Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally,
+ and don't include <sys/file.h>).

+
+ * getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin.
+ [__linux__]: Allocate a big enough buffer for /proc/loadavg.
+ [!LDAV_DONE]: Avoid unused variable warning.
