You should probably say that this is from the F2K standard.  I'm also curious
what edition you have, and where you got it.  In my Sep 2002 draft there's a
lot of stuff between C567 and this restriction.

I'm interested in this, because I was looking for something like this when I
implemented kind suffixes for boz constants.  With this rule from the
standard, kind suffixes to boz-literal-constants seem superfluous, so maybe we
should remove them from our compiler before we release a compiler with an
unneeded language extension.  What do other people think?
