Look into cp/cvt.c, ocp_convert(). It already handles errors for enum to enum
conversion and integer to enum conversion, so you can add your warning there.
Googling a bit should give you at list one link to a patch adding a new warning
message (get something recent!), so that you see all the places you need to
updated.
Remember to work on mainline, not a release branch.
