Help: C++ virtual tables not created

Quite unlikely. More likely, you are getting the wrong header files
on openVMS.

AFAIK, g++ looks for some attributes of the class, and implements the
VT in the file which also has the attribute. A possible list is:
- first virtual function is implemented here
- first static member data is implemented here
- first non-inline constructor is implemented here
or the like. These are not the actual criteria used by g++, but you
get the idea.
