I suspect the implementors of PCC would be interested in hearing those "good
reasons", since PCC *does* implement the type "pointer to array", and if you
dereference something of that type it does yield an array (which gets
converted to a pointer into its first element, along the lines mentioned in
the ANSI C draft).  In fact, they had no choice *but* to implement that
type, since K&R clearly indicates that "pointer to array" is a valid type
(an example is given of a pointer of that type in the C Reference Manual).
It is a nuisance to generate a *value* of that type to assign to a variable
of that type, but that's another matter.
