Indeed, it turns these two into links to their definitions.

Let me stress first, that I just apply some of the parts of gtk-doc
manual here.

For example, one of the recent ""fix" check-doc-syntax commits patches"
(caa4c9fdeb3aecd9a4288114e75d24ec931cd01b), did contain fixes for the
script warnings, but those were rather irrelevant for gtk-doc itself.
'**/' at the end is at best a style fix, as gtk-doc is interested only
in '/**' at the start (or is that something for the script itself ?).
Trying to document a *private* function (at least anywhere outside
the source) is a rather odd idea (and at best that only created
a stray file in xml/).

check-doc-syntax.sh runs on sgml templates.
There's that 40d6c580cd029f3d330ba28a7728ff36498920cb commit
(configure.ac: Do not generate template files when building docs), so 
- to a point - this has already been accepted in the past.
Given that commit, cairo shouldn't be generating the templates already.
It does only cause instead using the upstream gtk-doc.make it uses its
own copy to implement support for out-of-tree doc builds (which is
actually a very nice feature).

Now, add one more thing: in NEWS for gtk-doc 1.21, it has been clearly
stated, that the whole infra for generating the templates is planed to
be axed in the next release. Yeah, I know how it is with plans (the same
warning was in the previous release already, so they may reschedule again),
but that's still a pretty big warning, especially that the upstream
has discouraged the use of templates for a few years already.

:growl: Let's start with simple facts:
1. as it's '#if 0' it effectively doesn't exist
2. as it's not mentioned in doc/public/cairo-sections.txt, it does not
exist in the docs (which, given 1, is a good thing)
3. given 2, it serves only as a source of gtk-doc warnings

Not that such function wouldn't be useful in some cases, but sprinkling
references to non-existant functions gives you only *misleading* docs.
