pathnames.
With the current API (no *at functions), FTS_NOCHDIR requires that the
fts_accpath start with the original path passed to fts_open(); therefore,
the depth that can be reached is limited by the {PATH_MAX} constraint on
this pathname.

example, it uses a serialization point like following:
pthread_mutex_lock(&mutex);
pthread_mutex_unlock(&mutex);
pthread_mutex_destroy(&muetx);
They think a previous lock holder should have already left the mutex and
is no longer referencing it, so they destroy it. To be maximum compatible
with such code, we use IA64 version to unlock the mutex in kernel, remove
the two steps unlocking code.
Just like kill(2), it is impossible for killpg(0, ...) to fail with
ESRCH, as a process always has a process group.

On FreeBSD, all processes have a process group, so it is impossible for
kill(2) to fail this way. POSIX also doesn't mention this error
condition.

TOC sections (e.g. GCC), leading to a segmentation fault. Adding -mlongcall
to crt1 flags causes the compiler to emit explicit TOC load instructions
for all function calls, including _fini().

Mark new crt1 with FreeBSD-specific ELF note.
Move some common crt1 code into new MI file ignore_init.c, to reduce
duplication. Also, conservatively adjust nearby sources for style.

So increment calculated static size by the size of it.
syscall. Before r5958, seekdir() was called for its side effect of
freeing memory allocated by opendir() for rewinddir(), but that revision
added _reclaim_telldir() that frees all memory allocated by telldir()
calls, making this call redundant.
This introduces a slight change. If an application duplicated the descriptor
obtained through dirfd(), it can no longer rely on file position to be
reset to the start of file after a call to closedir(). It's believed to
be safe because neither POSIX, nor any other OS I've tested (NetBSD, Linux,
OS X) rewind the file offset pointer on closedir().

They were made excessive in r205424 by opening with O_DIRECTORY.
Also eliminated the fcntl() call used to set FD_CLOEXEC by opening
with O_CLOEXEC.
(fdopendir() still checks that the passed descriptor is a directory,
and sets FD_CLOEXEC on it.)

get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.
Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang (disables -Werror)
- NO_WCAST_ALIGN.clang (disables -Wcast-align)
- NO_WFORMAT.clang (disables -Wformat and friends)
- CLANG_NO_IAS (disables integrated assembler)
- CLANG_OPT_SMALL (adds flags for extra small size optimizations)
As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf! For clang, use the following:
CC=clang
CXX=clang++
CPP=clang-cpp
