Hmm. I wonder if its a problem with C++ having a runtime that needs to
be initialized. You would have trouble like that if you tried calling
Ada from another language. But Ada provides a routine with a standard
link name that you can call to initialize everything.

Try changing the const variables to #defines, and see if you get the
right value. If that works, you either need to figure out how to call
C++'s initialization code directly, or you need to find some compile
option that causes those variables to get loaded with the right value.

"pragma interface_name" is a Gnat-specific pragma to allow backwards
compatability with some old DECAda code. Unless that is your situation,
you should be using
   pragma import (C, SUB_C, "sub_c");
instead. Changing it won't fix your current problem though.
