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

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.

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.

was rejected as a range error, while any values less than LONG_MIN
were silently substituted with LONG_MIN. Furthermore, on some
platforms `time_t' has less range than `long' (e.g. alpha), which may
give incorrect results when parsing some strings.
strange things might happen when garbage values in the struct
get passed in to localtime_r() and family.

adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.
Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex

using them if possible.
Remove uneeded includes of <errno.h> from a few files.
