Compliance Definition. On sparc64, GCC emits _Qp_cmp() calls for its
__builtin_isfoo() functions which are used for C99's isfoo() macros.

around gcc optimization (thanks to cognet@).

for kldstat to ever print "IP Filter" (the module is called "ipfilter"
and modules don't have anything like a description), so this function
would always return false. That would cause prestart to attempt to
load the module even if it's already loaded, which would fail and
prevent the rules from being loaded.

using my own script to handle it. I wrote my own partially because
of all the quoting-issues involved with testing what I wanted to test,
and partially because this lets me commit one script and one data file,
instead of one-file-per-regression-test.
This suite was good enough for my initial testing (and it did help me
find a few bugs that would have otherwise been missed). I'm not sure
how well it will work in general use, but I figured I might as well
commit it. It won't *hurt* to have it available. At the worst, people
can just ignore it.

apart a string, and supports some text substitutions. This can be
used to provide all the flexibility (and more!) that was lost by recent
changes to how the kernel parses #!-lines in shell scripts.
The '-P' option provides a way to specify an alternate set of directories
to use when searching for the 'utility' program to run. This way you can
be sure what directories are used for that search, without changing the
value of PATH that the user has set. Note that on FreeBSD 6.0, this
option is worthless unless the '-S' option is also used.

without checking it for an equals-sign. If it starts with a slash, then
it cannot be a request to set the value of a valid environment variable.

it does not happen until all single-letter options are processed. This will
be important for the -S option, which will be coming soon.

#!-line had multiple whitespace characters after the interpreter name, and
it did not have any options, then the code would do nasty things trying to
process a (non-existent) option-string which "ended before it began"...

the traces it is clear that the buf is removed from the dirty queue while
it is actually on the clean queue which leaves the tail pointer set.
Assert that both flags are not set in buf_vlist_add and buf_vlist_remove.

cache_zap() to clear the v_dd pointers when a directory vnode is forcibly
discarded. For this to work, all vnodes with v_dd pointers to a directory
must also have name cache entries linked via v_cache_dst to that dvp
otherwise we could not find them at cache_purge() time. The following
code snipit could break this guarantee by unlinking a directory before
fetching it's dotdot. The dotdot lookup would initialize the v_dd field
of the unlinked directory which could never be cleared. To fix this
we don't initialize v_dd for orphaned vnodes.
