The patch works for me (no warning). The confusion about the warning probably 
arose because of the following line:

warning: Unused source { msvc%msvc.archive-bar.STATIC_LIB { 
msvc%msvc.compile.c++-bar.OBJ { bar.CPP } } } in main target ./foo

I saw "Unused source" and scanned the rest for some "source" that could be 
"unused" while it was not refrering to "source file" but to a source in general.
