True!  I just meant that every "Hello, world" program I've ever seen uses 
endl, and that if you were going to write out a \n instead you'd just 
stick it in the string rather than writing out a separate \n.  No matter.

Anyway, it seems you can work around the bug, at least in this instance, 
by including a dummy function in the header file like so:

    inline void foo() { std::cerr << std::endl; }

I'm not nearly smart enough to find a real solution, which probably 
involves fixing a missing find_substitution somewhere...
