**environ entries. This puts non-getenv(3) operations in line with
getenv(3) in that bad environ entries do not cause all operations to
fail. There is still some inconsistency in that getenv(3) in the
absence of any environment-modifying operation does not emit corrupt
environ entry warnings.
I also fixed another inconsistency in getenv(3) where updating the
global environ pointer would not be reflected in the return values.
It would have taken an intermediary setenv(3)/putenv(3)/unsetenv(3)
in order to see the change.
related to DNSSEC validation on a resolving name server that allows
access to untrusted users. If your system does not fall into all 3 of
these categories you do not need to update immediately.
execvPe() is called by _execvpe(), which we added to implement
posix_spawnp(). We just took execvP() and added the envp argument.
Unfortunately we forgot to change the implementation to use envp over
environ.
This fixes the following piece of code:
| char * const arg[2] = { "env", NULL };
| char * const env[2] = { "FOO=BAR", NULL };
| posix_spawnp(NULL, "/usr/bin/env", NULL, NULL, arg, env);

FTS_NOCHDIR option is used. fts_build() could strip a trailing slash
from path name in post-order visit if a path pointing to an empty
directory was given for fts_open().

provided to ease porting from System V-like systems. Since sigpause
already exists in compat with different interface, XSI sigpause is
named xsi_sigpause.

The clang static analyzer erroneously thought that nsec can be used

the code clearer. (Clang can't know that sprintf() won't modify *pi

a feature that libstdc++ depends on to simulate the behavior of libc's
internal '__isthreaded' variable. One benefit of this is that _libc_once()
is now private to _once_stub.c.

with the additional property that it is safe for routines in libc to use
in both single-threaded and multi-threaded processes. Multi-threaded
processes use the pthread_once() implementation from the threading library
while single-threaded processes use a simplified "stub" version internal
to libc. The libc stub-version of pthread_once() now also uses the
simplified "stub" version as well instead of being a nop.
