it for Android, but we've had this in released NDKs for years now so

The 2016f release of the tz code and data is available. It reflects the
following changes, which were either circulated on the tz mailing list
or are relatively minor technical or administrative changes:
Changes affecting future time stamps
The Egyptian government changed its mind on short notice, and
Africa/Cairo will not introduce DST starting 2016-07-07 after all.
(Thanks to Mina Samuel.)
Asia/Novosibirsk switches from +06 to +07 on 2016-07-24 at 02:00.
(Thanks to Stepan Golosunov.)
Changes to past and future time stamps
Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone
abbreviations instead of invented ones.
Changes affecting past time stamps
Europe/Minsk's 1992-03-29 spring-forward transition was at 02:00
not 00:00.
(Thanks to Stepan Golosunov.)
Note: Paul Eggert changed the key used to sign the tzdata bundle and
the new public key cannot be found. The changes to the data since
2016e have been verified visually.

Before, dynamic executables would initialize the global stack protector
twice, once for the linker, and once for the executable. This worked
because the result was the same for both initializations, because it
used getauxval(AT_RANDOM), which won't be the case once arc4random gets
used for it.

* changes:
Defer registration of the arc4random fork-detect handler.
Make getpid work before the main thread is initialized.
Take the arc4random lock before forking.
Previously, arc4random would register a fork-detecting pthread_atfork
handler to not have to call getpid() after a fork. pthread_atfork uses
pthread_mutex_lock, which requires the current thread to be initialized,
preventing the use of arc4random for initializing the global stack guard,
which needs to happen before the main thread has been initialized.
Extract the arc4random fork-detection flag and use the existing
arc4random fork handler to set it.

Guess October 27 and 24:00 transitions. (Thanks to Steffen Thorsen.)
For future years, guess April's last Thursday to October's last
Thursday except for Ramadan.
Changes affecting past time stamps
Locations while uninhabited now use '-00', not 'zzz', as a
placeholder time zone abbreviation. This is inspired by Internet
RFC 3339 and is more consistent with numeric time zone
abbreviations already used elsewhere. The change affects several
arctic and antarctic locations, e.g., America/Cambridge_Bay before
1920 and Antarctica/Troll before 2005.
Asia/Baku's 1992-09-27 transition from +04 (DST) to +04 (non-DST) was
at 03:00, not 23:00 the previous day. (Thanks to Michael Deckers.)

Move the various synonyms for __attribute__(__whatever__) together.
Fix a __STDC__VERSION__ (for __STDC_VERSION__) typo.
Drop support for BSD _ANSI_SOURCE and _C99_SOURCE; there's enough confusing
nonsense here already, and plenty of other ways to ask for obsolete standards.
There are plenty more problems here -- what I really want to do is rationalize
our treatment of __STDC_VERSION__ -- but let's get some of this easy stuff
out of the way first.

http://clang.llvm.org/docs/AttributeReference.html#nonnull
_Nonnull is similar to the nonnull attribute in that it will instruct
compilers to warn the user if it can prove that a null argument is
being passed. Unlike the nonnull attribute, this annotation indicated
that a value *should not* be null, not that it *cannot* be null, or
even that the behavior is undefined. The important distinction is that
the optimizer will perform surprising optimizations like the
following:
void foo(void*) __attribute__(nonnull, 1);
int bar(int* p) {
foo(p);
// The following null check will be elided because nonnull
// attribute means that, since we call foo with p, p can be
// assumed to not be null. Thus this will crash if we are called
// with a null pointer.
if (src != NULL) {
return *p;
}
return 0;
}
int main() {
return bar(NULL);
}
Note that by doing this we are no longer attaching any sort of
attribute for GCC (GCC doesn't support attaching nonnull directly to a
parameter, only to the function and naming the arguments
positionally). This means we won't be getting a warning for this case
from GCC any more. People that listen to warnings tend to use clang
anyway, and we're quickly moving toward that as the default, so this
seems to be an acceptable tradeoff.
