Use
...
.In header.h
instead of
.Fd #include \*[Lt]header.h\*[Gt]
Much easier to read and write, and supported by groff for ages.
Okayed by ross.

1003.1-2001 has introduced unsetenv() which differs from the current
...
implementation in not permitting a "name=value" argument.
* Add a conforming __unsetenv13() and do function renaming for
unsetenv(); preserve old symbol with old behavior.
* Make visible setenv() and unsetenv() for 1003.1-2001 feature selection
macros; resolves PR standards/20479.

When implementing a recursive mutex, it helps if you remember to
...
decrement the recursion count.
Fixes the problem of uic dying with a no-next-thread assertion while
building kdeadmin3; reported by Perry Metzger and others on
tech-pkg.

Don't acquire __environ_lock around exec*() calls; nothing requires
...
that these calls be thread-safe with respect to the environment, and it
causes serious problems for threaded applications which call vfork() and
exec*() (including indirectly, via popen() or system()).
Acquire and release __environ_lock in the parent in popen() and system() to
play safe and provide the child with a stable environment.
__environ_lock should also have an atfork() handler; still under development.

Fix lib/20558:
...
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler. This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle. By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).
Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

Rewrite atexit(3), and add support for __cxa_atexit()/__cxa_finalize(),
...
as specified by the C++ ABI for Itanium. Despite the ABI document's name,
many of the items in it are implemented for other architectures.
