truncation if $TMPDIR is set; also, fix an error path to not leave the
temporary file behind. From Gao Ya'nan in PR 39746.
While here, use _PATH_TMP instead of a hardwired "/tmp".
previous versions, when we know we're working on an old file. That way,
a -current config(1) works on a 4.0 source tree (or older) without
warning. Pointed out by Christos Zoulas.
XXX We should set up way to note compatibility code we can get rid of
XXX the day we choose to bump CONFIG_MINVERSION.
The rule is, if you change scan.l or gram.y, you bump the config(5)
version. If you implement the changes under sys/conf/files or affiliate,
you bump the required version in sys/conf/files or in an appropriate place
to minimise annoyance. If the changes makes new config(1) incompatible
with a previous version of config(5), embed it in config(1) using the
CONFIG_MINVERSION definition along with CONFIG_VERSION.
This has been in the tree for what, 3 years now? It's even documented...
ones, mostly network pseudo interfaces) and those which use autoconf
to attach instances dynamically, or to attach child devices.
Use a new keyword "defpseudodev" for the latter.
Issue a warning if interface attributes are used with "old" pseudodevs,
but let it work as before for now. This will be removed soon.

that uses each configuration parameter.
This will stop kernel objects build with different options (that come from
config files) being linked together or loaded as a LKM.
Currently some options that have an effect on the kernel DDI/KI are passed
directly as parameters to cc.
An aim (for anyone adequately bored) would be to reduce the number of these
constants that appear in each .o file. .o files with the same constants
should be sharable between kernels (even between XEN and i386).
configuration file (although it is meant to be used mostly with
std.${ARCH}), and prints out a configuration file that includes it and
select every single option and parameter, and define an instance for every
single possible attachment. IOW, selects everything, into a would-be
"LINT" config.
The resulting config really isn't meant to be runnable, but should be
somewhat buildable on most archs. It still needs adjustments because some
options are peculiar (e.g., ACPI_DSDT_FILE wants an existing file as its
value), so it's not yet possible to do "config -L; config; build" in an
automated way.
- Move documentation for "package", because as I learned tonight, it's not
allowed before setmachine. You get to discover scary new stuff about
config(1) each time you look at it.
It caused config(1) to crash on the following assert() if the list was used.
This bug shows up after the recent change in files.c which fixed a memory leak.

call - which makes the code completely impossibly to follow, call fflush()
and ferror() just prior to calling fclose().
This has the advantage of actually detecting the any write errors, since
the output is block bufferred and will typically not happen during fprintf()
but only during the fclose() - where it is difficult to report.
I also singlilarly refuse to add (void) casts to every printf call in the
system - since it almost never makes any sense to look at the return value
(unless you want to know how many bytes were actually writtem).
