This was an intentional omission - when looking for documentation of
the pragma in clang I found none.

If we do want to document the pragmas in GCC:
 - what section of the documentation would that go in?
    - gcc/doc/cpp.texi, section 7, "Pragmas"
        - this section states: "This manual documents the pragmas
which are meaningful to the preprocessor itself. Other pragmas are
meaningful to the C or C++ compilers. They are documented in the GCC
manual."
        - these pragmas aren't exactly meaningful to the preprocessor
_or_ the C/C++ compiler, so it's not exactly clear where they fit.
    - gcc/doc/extend.texi, section 6.62, "Pragmas Accepted by GCC"
 - what exactly would it say?
    - I guess just mention the existence and that they won't trigger
unknown pragma warnings? They don't _do_ anything
