Suppose I'm writing a program in both C and C++, and I've got globals
requiring compile-time initialization in both.  Then both languages will
want to own "main" (i.e., have main written in their language).  Is there a
nice way to solve this problem, particularly if, say I'm including two
read-only modules, one in each language (i.e., I can't change the source)?

I assume that both languages generate a routine "real_main" (often called
_main) that looks like this:

    real_main()
    {
      initialize_globals();
      main();
      cleanup_after_globals();
    }

However, only one real_main() will get called, the one belonging to
whichever language writes main.  Is there a portable solution?
