Description
In firefox code, we use some macros to make annotations (for clang static analysis for example).
For example:
https://searchfox.org/mozilla-central/source/dom/animation/AnimationTarget.h#54
or
https://searchfox.org/mozilla-central/source/mfbt/CheckedInt.h#510
Such annotations lead to parse errors and I understand that (because likely this comment itself is valid C++/C: we just have to define some good macros).
So is it something tree-sitter-c/cpp could handle or should I have my own grammar for this code ?
I'd prefer of course the former.

Research direction
Start with the annotation examples in dom/animation/AnimationTarget.h and mfbt/CheckedInt.h referenced in the issue, then inspect how tree-sitter-c/cpp handles the corresponding macro syntax. Confirm the expected behavior with a minimal parser case; done means establishing whether the existing grammar can parse these annotations or a separate grammar is required.
