in ports
Even if those _[BCNLPSUX] defines are in the reserved namespace, some
ports make use of those identifiers and thus need pointless
headscratching and patches. Just use a longer reserved prefix.
We can't just #undef those defines as they are used in libc.
Change similar to what NetBSD did around 2010. Went through base builds
and an amd64 bulk build, the only fallout was lib(e)stdc++ base_ctype.h.
"make includes" will install the latest ctype.h and libstdc++ ctype_base.h.

it is a dangerous alternative entry point for all system calls, and thus
incompatible with the precision system call entry point scheme we are
heading towards. This has been a 3-year mission:
First perl needed a code-generated wrapper to fake syscall(2) as a giant
switch table, then all the ports were cleaned with relatively minor fixes,
except for "go". "go" required two fixes -- 1) a framework issue with
old library versions, and 2) like perl, a fake syscall(2) wrapper to
handle ioctl(2) and sysctl(2) because "syscall(SYS_ioctl" occurs all over
the place in the "go" ecosystem because the "go developers" are plan9-loving
unix-hating folk who tried to build an ecosystem without allowing "ioctl".

of the C language but are part of the C library and have to be
declared in <uchar.h> - see paragraph 7.28.2.
In stark contrast, according to the C++11 standard, char32_t and char16_t
are part of the C++ language, namely, keywords - see paragraph 2.12.1.
Consequently, they must not be declared in a header file.
To resolve this vile contradiction, use the predefined macro __cplusplus
to find out which language is in use for the current compilation unit -
see C11 paragraph 6.10.8.3 and C++11 paragraph 16.8.1.

it discards its contents and returns immediately.

On BSD, fpos_t is typedef'd to off_t but some systems use a struct.
This means fpos_t is not a portable function argument or return value.
Both FreeBSD and the Linux libbsd funopen() have switched to off_t
for this--we should too. From Joe Nelson. OK deraadt@

libc can't do DNSSEC validation but it can ask a "security-aware"
resolver to do so. Let's send queries with the AD flag set when
appropriate, and let applications look at the AD flag in responses in
a safe way, ie clear the AD flag if the resolvers aren't trusted.
By default we only trust resolvers if resolv.conf(5) only lists name
servers on localhost - the obvious candidates being unwind(8) and
unbound(8). For non-localhost resolvers, an admin who trusts *all the
name servers* listed in resolv.conf(5) *and the network path leading to
them* can annotate this with "options trust-ad".
AD flag processing gives ssh -o VerifyHostkeyDNS=Yes a chance to fetch
SSHFP records in a secure manner, and tightens the situation for other
applications, eg those using RES_USE_DNSSEC for DANE. It should be
noted that postfix currently assumes trusted name servers by default and
forces RES_TRUSTAD if available.
RES_TRUSTAD and "options trust-ad" were first introduced in glibc by
Florian Weimer. Florian Obser (florian@) contributed various
improvements, fixed a bug and added automatic trust for name servers on
localhost.

We need to test what the compiler supports, not what the C library
provides. This prevents static_assert from being defined when compiling
with the in-tree gcc (4.2.1) which does not support _Static_assert.

be 8 bytes in the 64-bit ABI just like in the 32-bit ABI. But that means
there is no "spare" word in the TCB that we can use to store a pointer
to our struct pthread. So we have to treat powerpc64 special.
Also recognize that the thread pointer points 0x7000 bytes after the TCB.
Since the TCB is 8 bytes this means that TCB_OFFSET should be 0x7008.

The API exposes controls of modern audio hardware and sndiod software
volume knobs in a uniform way. Hardware knobs are exposed through
sndiod. Multiple programs may use the controls at the same time
without the need to continuously scan the controls.
For now sndiod exposes only its own controls and the master output and
input volumes of the underlying hardware (if any), i.e. those
typically exposed by acpi volume keys.

- put functions and data which are only used before calling the executable's
start function into their own page-aligned segments for unmapping
(only done on amd64, arm64, armv7, powerpc, and sparc64 so far)
- pass .init_array and .preinit_array functions an addition argument which
is a callback to get a structure which includes a function that frees
the boot text and data
- sometimes delay doing RELRO processing: for a shared-object marked
DF_1_INITFIRST do it after the object's .init_array, for the executable
do it after the .preinit_array
- improve test-ld.so to link against libpthread and trigger its initialization
