No worries.  In theory, if the DLL you're linking against is not too
old, you could omit it from your own package.  For instance, for
the ncurses library, the DLLs are still available back to libncurses5,
from back in 2003.  If that's too dangerous for you, you can just add
them to your package since there should be no conflict.
