HEARTBREAKING: "common initial sequence" does not apply to two unrelated structs not copied into a union, and therefore any old pointer cast form one struct to another to inspect the common initial sequence is ACTUALLY illegal as hell! This sucks! This REALLY sucks! - ThreadSky

Yes. It's always been broken.

That's why I would pay actual money for this to become standard C https://gcc.gnu.org/onlinedocs/gcc-5.3.0/gcc/Unnamed-Fields.html

Is there a C-standard-bananas escape hatch (like memcpy, or a union of structs, ...)?

ON THE BRIGHT SIDE: "first member of a structure is identical to the address of the structure" actually provides enough of a foundation for this to work, so I'm gonna do that.
