Agreed.

I am not convinced that is true for "all Ada compilers".  I cannot think
of a reason why it should be true for DEC Ada, and looking at the Run-Time
Reference Manual for running on VMS, I do not see such a restriction in
the chapter on mixed language programming. (The Run-Time library for
DEC Ada is included by the linker, regardless of the language for the
main program.)

If anyone knows of a failure of this sort for DEC Ada running on VMS,
I would be interested to hear about it.
