But Ares is built one object at a time via a makefile, so there are no
"multiple sources given on the command line." Did you mean, perhaps,
that this is somehow related to how DMD treats modules vs. how DMC
treats source files? ie. that the #include model effectively
copy/pastes code while importing modules does not?
