Then don't! Here's a simple formula that works: Link C programs with
gcc; link C++ programs with c++ or g++ (which are the same thing)
to get the C++ runtime libraries automatically linked in; link f77
programs with g77. 

If you want to do anything else, then you have to figure out the runtime 
libraries needed for each language and provide them yourself. (Hint: C++ 
programs usually need -lstdc++).

The above should give you the clue needed. You misunderstand the implication 
of "-x c++" option.

Nothing bizarre here. It's expected and documented behaviour.
