We currently have a page for tracking defects against the C++ standard,
but we don't have the same information for the C standard. This starts
us down the path of being able to track that in a way our users can see.
There are *a lot* of entries marked as "Unknown". As we validate
Clang's behavior for a given DR by adding a test case for it, we can
slowly begin to improve this page over time.
This page is now linked from the existing C status page, which was
updated slightly as a result of these changes as well.
Note, unlike with the C++ defect report page, this content is not auto-
generated from a source document and is not automatically updated from
test comments. It may be worthwhile to automate the updates based on
our test coverage, but that can happen later.
WG14 has elected to remove support for K&R C functions in C2x. The
feature was introduced into C89 already deprecated, so after this long
of a deprecation period, the committee has made an empty parameter list
mean the same thing in C as it means in C++: the function accepts no
arguments exactly as if the function were written with (void) as the
parameter list.
This patch implements WG14 N2841 No function declarators without
prototypes (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2841.htm)
and WG14 N2432 Remove support for function definitions with identifier
lists (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2432.pdf).
It also adds The -fno-knr-functions command line option to opt into
this behavior in other language modes.

This completes the implementation of
WG14 N2412 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2412.pdf),
which standardizes C on a twos complement representation for integer
types. The only work that remained there was to define the correct
macros in the standard headers, which this patch does.
Although we moved to Github Issues. The bug report message refers to
Bugzilla still. This patch tries to update these URLs.

This doesn't add all of the document numbers, but it adds a bunch of
them. Not all of the documents are available on the committee page
(they're old enough that they come from a time when the mailing was
comprised of physical pieces of paper), so some of the documents listed
are assumed to be correct based on my reading of editor's reports.
This adds implementation information for N2607,
clarifies that C17 only resolved defect reports,
and adds -std= information for the different versions.
