> Please add a comment that lays out our reasoning for the prohibition against combining PARAMETER and POINTER, since the standards do not explicitly preclude it.  (The PARAMETER attribute requires a entity-decl to have an initialization that is a constant-expr, and the only form of initialization that allows a constant-expr is the one that's not a "=>" pointer initialization.)  See C811, C807, & 8.5.13.

Thanks for the detailed reasoning.  I'll add a comment.
