gEDA-user: Why does DRC check annular ring twice?

[Ben Jackson <ben@xxxxxxx>]

The DRC checks the annular rings of vias against both the 'minWid'
and the 'minRing'.  The rules I'm working with are 6/6 with a 5mil
annular ring.  I'm working with minimal vias to do routing to a QFP.
The DRC notices that all of my annular rings violate the minimum trace
width.

Why have a 'minRing' at all if vias are going to be subject to the
minimum trace width too??
