Using [[may_alias]] in C23/C++23 on a union works in neither post-"union" position, or at the end of the definition

Oh, D'oh! Thanks Joseph, apologies for the needless email on the list then.

One final question if I could -- does that mean that in order to support
"may-alias" with the bracket syntax on both Clang and GCC, it would require:

 union [[gnu::may_alias]] [[clang::may_alias]] foo {};
