finding casts from a type

[Brooks Davis]

I'm trying to figure out an efficent way to find all the places where a
given type (in my case struct ifnet *) is cast to another.  Does anyone
know of a tool to do this?  I need to include implicit casts to (void
*). I could do it by hand, but this is would be tedious and error prone
given that there are over 330 files that refrence struct ifnet in the
kernel.  The ideal solution would be a pragma or something to cause
gcc to generate a warning since once I move struct ifnet out of driver
softc's all casts will be bugs.  Initially I need to catch (void *)
casts, but that probably won't be necessicary long term.
