--- Comment #10 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Well, so far my plan is to gather symbols in #pragma GCC may_alias SYMBOL to some vector of symbols and then when declaring a SYMBOL check if it's in the vector and if so, apply the may_alias attribute. Now, as Richi points out, I'll probably have to introduce two variants: #pragma GCC may_alias SYMBOL #pragma GCC may_alias struct SYMBOL The symbols in the vector would serve as a "tentative" forward declaration. Do you see any problems with that?
