No, the two are mutually exclusive.

If you use neither weights= nor -c, you get a square neighbourhood. If
you use -c, you get a circular neighbourhood. If you use weights=, the
values in the weights file determine the shape of the neighbourhood. 
If you use both -c and weights=, you get an error.
