Any chance of adding something like:

to the .dbd->.h conversion so that there's a count of menu entries for each
menu?

There might be, but we (Marty and I) are not sure how necessary it really
is. Can you explain why you need it, and how you'll work around its
absence from the version of Base that you're currently using?
One way to get the number of choices from a menu definition at runtime is
something like:
    #include "dbStaticLib.h"
..
    int count = dbFindMenu(pdbbase, "menuName")->nChoice;
My guess is that if we accept it we would add your suggestion to R3.14 but
not R3.13. We'd probably also add equivalent code to dbToMenuTypeH.c for
uniformity.
We're trying to avoid adding stuff that "might be useful" but which isn't
actually needed in practice. I'm also slightly concerned about the
generated name clashing with some existing menu that already defines a
<menuName>_Count choice, although there aren't any in Base so it probably
wouldn't be a problem.
