I take the point that in these cases only a single CU is loaded. While
currently GDB does not consider such CU for language detection (such as
because it does not contain `main') one possible fix is to just follow the CU
language, if it is the only CU loaded.

There was another mail about use case when you combine C/C++ application/libs.

What are disadvantages of interpreting something as C++ instead of giving
error on such expression?
