Some sample uses: controlling USB speakers with the HID buttons on them,
invoking the proper programs from the HID buttons on modern USB
keyboards.
use -j; all make's in a recursive build cooperate to limit the total
number of jobs, using a token-passing scheme.
The current token passing algorithm is similar to the one implemented
by gmake; there is a single pipe which is inherited through the entire
process hierarchy; tokens are obtained by reading a byte from the
"read end" of the pipe, and are returned by writing them to the "write
end". This exact algorithm is likely to change in the future.
Implementation details:
- Use the new trace facility to allow measurement of the
effectiveness of different token-passing schemes
- Get a token in MakeStartJobs(), return it in Make_Update()
- Eliminate Job_Full() and the jobFull global since they are
redundant with token system.
- Add an "internal" -J option (to pass the token pipe fd's down to
submakes) and a -T option for tracing.
- Change how compatMake is forced so that -j means something when
inherited by submakes.
- When waiting for a token, poll the token-passing pipe as well as
the output pipes of existing jobs.
if there are any mistakes, please report (i only speak English/Japanese).
currently, only singlebyte locales are usable.
TODO: enable multibyte handler in libc - there still are few design
discussions, but we are almost ready.
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.

- rename audio_get_sun_encoding() to audio_sun_to_encoding()
- add audio_encoding_to_sun()
play.c:
- adapt
record.c:
- convert NetBSD encoding to sun encoding if possible, otherwise don't
output a header at all.
fixes PR#10380 from Michael Eriksson <eramore@era-t.ericsson.se>.
poll() for parallel make:
- Make the poll() code behave more like the select() code: sleep for
a bit waiting for output rather than busy-wait (eww).
- Install a no-op SIGCHLD handler so that poll/select wake up early
(with -1/EINTR) when a child exits.
- Change the default sleep time from 500ms to 5 seconds since we now
wake up promptly when a child exits.
try to open tfile many times, passing bad strings to mkstemp
2. remove extra semicolon after the MESSAGE macro
3. more error checking
4. be more careful about setting things to NULL after freeing.
5. fix a comment that does not apply anymore
