pointers to arrays and the '&' operator

All the versions of the dpANS that I've seen allow you to apply "&" to
an array; I would be extremely surprised if the latest version of the
pANS didn't permit you to do so as well.  The reason why you're not
generally permitted to do this on, say, UNIX systems is that many C
compilers on UNIX systems don't implement that part of the language in
the dpANS (e.g. the Ritchie compiler, or PCC).

The May 19, 1988 dpANS indicates that "function designators" don't get
turned into "pointer to function" expressions when used as the operand
of "sizeof" or unary "&", so that version (and presumably later
versions) of the (draft) proposed standard allows you to do &E as well.
