I don't know what "it" refers to here, but if "it" is an assignment of a
pointer to an array of X to a pointer to a pointer to X, or something like
that, the reason why the PCC in question (and most other PCCs) passed it is
that PCC has a bug in it.  The type checking code in "chkpun" is completely
wrong.  It treats pointers and arrays as equivalent everywhere.  See
net.bugs.v7/net.bugs.2bsd/net.bugs.4bsd and net.bugs.usg for fixes.
