Ruby was built with LibreSSL.
C++ keyword `nullptr` represents a null pointer (note also that NULL is
an integer in C++ due to its design flaw). Its type is `std::nullptr_t`,
defined in <cstddef> standard header. Why not support it when the
backend implementation can take a null pointer as an argument.
BSD make can run parallel more aggressively than GNU make. It communicate
with other make process through -J option in MAKEFLAGS environment variable
to notify a build failure happend in an other pararell make process.

It usually works well but ext/-test-/cxxanyargs/Makefile has two targets
which are expected to fail (failure.o and failurem1.o).
Additional note:
To test and debug this issue, following command will speed up it.
`make -f exts.mk -j8 clean all`
This removes the warnings added in 2.7, and changes the behavior
so that a final positional hash is not treated as keywords or
vice-versa.
To handle the arg_setup_block splat case correctly with keyword
arguments, we need to check if we are taking a keyword hash.
That case didn't have a test, but it affects real-world code,
so add a test for it.
This removes rb_empty_keyword_given_p() and related code, as
that is not needed in Ruby 3. The empty keyword case is the
same as the no keyword case in Ruby 3.
This changes rb_scan_args to implement keyword argument
separation for C functions when the : character is used.
For backwards compatibility, it returns a duped hash.
This is a bad idea for performance, but not duping the hash
breaks at least Enumerator::ArithmeticSequence#inspect.
Instead of having RB_PASS_CALLED_KEYWORDS be a number,
simplify the code by just making it be rb_keyword_given_p().
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
* Default VMIN and VTIME to minimum input.
* Disable parity check bits explicitly.
* Disable all bits for flow control on input.

TCSAFLUSH discards the buffer read before the mode change, which makes
IRB ignore the buffer input immediately after invoked. TCSANOW
preserves the buffer.
