gcc 11.x - error: size of array element is not a multiple of its alignment

[thkukuk]

With current gcc 11.x you get an error when compiling asignify.
I found more details in this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1937076

A possible fix could look like according to that bug report:
