Clarification on who can approve Objective-C/Objective-C++ parser patches

[Nicola Pero]

Most of the Objective-C/Objective-C++ parser code is in files shared with the C/C++ frontend,
hence I'm confused about who approves what.

For example, if I post a patch that changes a piece of code in gcc/c-parser.c which is only
ever used if (c_dialect_objc ()), then I assume that it is part of the Objective-C
front-end, and the Objective-C/Objective-C++ maintainers are in charge of approving it.  Once
they approve it, I can commit.

Is that correct ?

Do I need to wait for approval from the C/C++ frontend maintainers as well even if the execution
path is only ever used when parsing Objective-C/Objective-C++ ?

Thanks

PS: Obviously I'm very happy to address any concerns anyone may have with any patch, and I won't commit any patch
where there is any objection (certainly not from a C/C++ frontend maintainer), but my question is mostly about
what I am supposed to do if the Objective-C/Objective-C++ maintainer approves my patch and nobody else says
anything.
