> non-standard extension and thus not portable

Modern versions of standard C aren't very portable either, unless you plan to stick to the original version of K&R C you have to pick and choose which implementations you plan to support.

I disagree. Modern C with C17 and C23 make this less of an issue. Sure, some vendors suck and some people take shortcuts with embedded systems, but the standard is there and adopted by GCC, Clang and even MSVC has shaped up a bit.

    Well, if that is the standard for portability then may_alias might as well be standard. GCC and Clang support it and MSVC doesn't implement the affected optimization as far as I can find.
