Eric, take a look at bug #53431, I think that's what you meant. It's a pretty
similar report about in-source pragmas not working in C++.

Further, that thread contains a WIP patch from Manuel López-Ibáñez, which he
expressly abandoned while encouraging others to finish and merge it.

P.S.
I do harbor a hope to resolve this on my own, once I accumulate the necessary
courage to allocate some time for a little GCC contribution. That's why I'm
reporting a separate issue knowing it's a duplicate :)
