My impression was, that GCC does not and actually never supported
attributes assigned to types. It worked by accident.

Like avr-libc fixed this by removing those types, we should remove them
too. Setting __PROG_TYPES_COMPAT__ is not a fix, but a work-around to
compile old code.

This is the place where I got my informations from. There are also
several related and excellent posts in the AVR GCC forum at avrfreaks.net.
