Yes, was I pasted was a local change. I was trying to eliminate the 
implicit cast to int from the enum type, which was causing my 
--enable-werror build to fail. At this point, I think the better 
option would be to break up the enum values into indivdual #defines and do 
a typedef df_changeable_flags int;

Sorry, I didn't mean to imply I was working on the now-dead branch. I'm 
doing this work in trunk. I want the build-as-cxx option to work decently 
so that my profiledbootstrap exercises the C++ front-end more, since that 
is what we compile all our code with here. As such, I'm building trunk to 
eliminate some of the cxx failures, and will submit a patch once it either 
builds completely or I've hit a brick wall. This should (hopefully) make 
for less work when the more invasive changes are started once trunk is 
open again.

PS: of course, it would be even better if profiledbootstrap allowed me to 
point at our build's makefile to generate the runtime profile.
