The longer name is more expressive and more correct. The previous name
called each stack element a stack itself, which was unnecessarily
confusing.
No functional change.
By listing the expected diagnostics directly at the code that triggers
the diagnostics, it is easier to cross-check whether the diagnostics
make sense.
No functional change to lint itself.
Several C99 tests do not actually test C99 features but instead GCC
features. All these tests should be double-checked again.
In some other tests, split the initializers into more lines, which makes
it easier to read the debug log corresponding to these tests. This will
be necessary for reworking the initializer code to actually conform to
C99.
It's too easy to forget one of them when adding or removing some lines.
This would make it more difficult to locate the lines referenced in the
error messages.

the common case (hw priority, no cascaded interrupts pending).
This also removes the need for the "pic_pending_used" flag, and should fix
booting on Raspberry Pi 3.
Right now, this variant of the popular macro pattern is flagged as
needing a /*CONSTCOND*/ annotation. As with 'do { ... } while (0)',
there is nothing wrong with this pattern, therefore there should be no
warning.
This is a preparation for allowing 'do { ... } while (false)', in
addition to the commonly used 'do { ... } while (0)', without declaring
the controlling expression /*CONSTCOND*/.
This is the central data structure of the initializations, it keeps
track of the objects that still need to be initialized. Seeing its
contents in debug mode helps in finding and understanding the still
incomplete C99 support.

TEXT_START_SYMBOLS so it misses out on the default definition of
this that does provide an __eprol symbol. Fixes linking of profiled

move the rearming of the cq after the refill of the rq.
this is the only real diff we have left outstanding on a box that
experienced rx lockups. since adding this change it's been happy
for the last 4 weeks and counting so far.
The previous code accepted '# 123 "file.c" 23' as specifying a system
header, just because that number ends with '3'. The original intention
was to compare the complete word, not its suffix. Fix that.
No practical change since the only flags that are used by GCC are all
single-digit.
This also changes the conditions to their positive form, which is easier
to read.
No functional change. The resulting binary would have been the same as
before, were it not for the changed line numbers in the lint_assert
calls further down in the code.
The intention of the getopt check was to analyze only those while loops
whose condition consists of the usual getopt call. For all other while
loops, ck.while_level was intended to stay at 0.
This was not the case in ckgetopt.c 1.2 and has been fixed in ckgetopt.c
1.3. The code did not document the intended invariants though, which it
should have done. This will be done in a follow-up commit.
