Add document numbers for the C99 status page.

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.

 <h2 id="c99">C99 implementation status</h2>
 
 <p>Clang implements a significant portion of the ISO 9899:1999 (C99) standard, but the status of individual proposals is still under investigation.</p>
-<p>Note, the list of C99 features comes from the C99 committee draft. A list of N-numbered documents for these features does not appear in either the standard or in any available editor's report, so this section does not track document numbers currently.</p>
+<p>Note, the list of C99 features comes from the C99 committee draft. Not all C99 documents are publicly available, so the documents referenced in this section may be inaccurate, unknown, or not linked.</p>
+<!-- http://www.open-std.org/jtc1/sc22/wg14/www/docs/n874.htm contains the
+     final editor's report of what's been added to C99, but it includes more
+     papers than are worth listing because it includes editorial and cleanup
+     proposals in addition to feature proposals. When a paper is not available,
+     I list the paper number from the editor's report, but do not hyperlink it.
+     When I can't map the feature back to a paper, I mark it as unknown. -->
 <p>You can use Clang in C99 mode with the <code>-std=c99</code> option.</p>
