And just to spell it out,

case ENUM_VALUE1:
	bla();
	break;
case ENUM_VALUE2:
	bla();
default:
	break;

is a fairly idiomatic way of indicating that not all values of the enum
are expected to be handled by the switch statement. 

I really hope the Clang folks are reasonable and merge your patch.

The burn out point is about enjoying your work and feeling that it
matters. It really doesn't make much difference if you're doing
something you don't like for 12 hours every day or only in shifts with
another maintainer. You'll dislike it either way.

Applying a real patch set and then getting a few follow ups the next day
for trivial coding things like fallthrough missing or static missing,
just because I didn't have the full range of compilers to check with
before applying makes me feel pretty shitty, like I'm not doing a good
job. YMMV.
