Not that it's relevant to Emacs, but I don't know which part of the
C standard would force a C compiler to layout all unions at an
"addressable" offset.  I mean, wouldn't it be valid for a compiler to
analyze the whole program and decide "oh, the code uses the union in
such a way that I can bit-align it to save some padding space and noone
will notice"?
