I concede.  But it wasn't pointer-vs.-array that threw me; f[] and *f are
identical, whereas f[5] and *f are NOT and neither are f[] = {3} and *f.
What threw me was getting my insides and outsides confused.  C declarations
are giving me gray hairs!  Anyone for Modula-2?

The declaration is correct, the cast should be to (double **), and MSC is as
screwed up as everything else I've ever seen from Microsoft.  (So what's
new?)  I'm interested in knowing why your sys5 passed it without an illegal
pointer combo message, though.
