This reduces build output, need for recalculating paths, and makes it clearer
which paths are relative to what areas in the source tree. The change in
performance over a locally mounted UFS filesystem was negligible in my testing,
but this may more positively impact other filesystems like NFS.
LIBC_SRCTOP was left alone so Juniper (and other users) can continue to
manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as
include Makefiles with custom options.

4) Fail with incomplete week (week 0) request and no such week in the
year.
5) Fix yday formula when Sunday requested and the week started from Monday.
6) Fail with impossible yday for incomplete week (week 0) and direct %w/%u

7) Shift yday/wday to the first day of the year, if incomplete week

POSIX treats negative time_t as undefined (i.e. may be valid too,
depends on system's policy we don't have) and we don't set EOVERFLOW
in mktime/timegm as POSIX requires to surely distinguish -1 return
as valid negative time from -1 as error return.
Almost never needed in real life because %s is tends to be
only one format spec.
1) Return code of gmtime_r() is checked.
2) All flags are set.

Add support for the missing POSIX-2001 %U and %W features: the
existing FreeBSD strptime code recognizes both directives and
validates that the week number lies in the permitted range,
but then simply discards the value.
Initial support for the feature was written by Paul Green.
David Carlier added the initial handling of tm_wday/tm_yday.
Major credit goes to Andrey Chernov for detecting much of the
brokenness, and rewriting/cleaning most of the code, making it
much more robust.
Tested independently with the strptime test from the GNU C
library.

The patch still needs to be more robust and it broke the
build on MIPS so revert it for now while all the issues
are fixed.

Posix strptime() requires support for %t and %n, which were added
to the illumos port. Curiously we were skipping white spaces by
default in most other cases making %t meaningless.
We now skip spaces in the case of the %e specifier as strftime(3)
explicitly adds a space for the single digit case.

lib/libc using a reach-over makefile.
A typical use-case is to build a standard ILP32 version and a COMPAT32

on signed integer overflow wrapping. Otherwise mktime(3) and timegm(3)
can hang, in case the timestamp passed in struct tm is not representable
in a time_t. Specifically, any timestamp after 2038-01-19 03:14:07, in
combination with a 32-bit time_t.
Note that it would be better to change the code to not rely on undefined
behaviour, but it is contributed code, and it is not entirely trivial to
fix the issue properly.

When parsing the month "juillet" (abbr "jul"), %B recognized it as
"juin" (abbr "jui") because the full name of the month names is
checked at the same time as the abbrevation.
The new behaviour checks the full names first before checking the
abbrevation names.

Upgrade of the tzcode from 2004a to 2009e.
Changes are numerous, but include...
- New format of the output of zic, which supports both 32 and 64
bit time_t formats.
- zdump on 64 bit platforms will actually produce some output instead
of doing nothing for a looooooooong time.
- linux_base-fX, with X >= at least 8, will work without problems related
to the local time again.
The original patch, based on the 2008e, has been running for a long
time on both my laptop and desktop machine and have been tested by
other people.
After the installation of this code and the running of zic(8), you
need to run tzsetup(8) again to install the new datafile.

that works well. This does reduce the dynamic range of tm_year from
about 2 billion years down to "only" about 9 million years. Please
contact me if this restriction poses a problem.
Due to the complexity of the code, I admit that I didn't trace down
what, exactly, was overflowing with longer bits. This fixes software
that we run on the embedded systems we have.
