Hi Ed,

I agree with Jaap regarding the replacing of the enum, but that's not
your fault, and I suspect the majority of the other enum-conversion
cases will not have this issue.

The rest of the patch looks fine to me, but I'm out of time for a
proper review+checkin right now.

Cheers,
Evan

Doing a little forensic work on the C++ incompatibilities still present in the code base, here are the types of issues of the 4919 "c++-incompat" lines in a compilation of the latest source using gcc on a Linux box (Fedora 17) (before this patch):

I do want to point out, however, that the way I chose to resolve the enum_conversion complaint was to change the type of one member of a struct from an enum type to an int.  The longer version of the rationale is in the bug report.  If we find this kind of patch acceptable, and desirable, I'll do more.
