Ahh, menu definitions in record types, now I understand your problem: In
3.14 each menu got a separate include guard in the generated *Record.h
file, e.g. the aoRecord.h file starts with:

Note that if you tried to create a menu named 'ao' in the aoRecord.dbd
file the include guard generated for the menu would prevent you from
loading the record type since the names would be the same.

You should not include your external *Menu.dbd file from within your
*Record.dbd file. Either keep it as a separate file (which must still be
loaded by the IOCs) or move the menu definition into the Record.dbd file
entirely (and rename the menu, the usual convention is for
record-specific menus to be named beginning with the name of the record
type, such as the menu aoOIF shown above). That solution can be made to
compile for both versions of Base.
