In maint-0.2.4, building with clang 3.2 on fedora, I get: ``` src/or/circuitbuild.c:1946:11: error: enumeration values 'PATH_STATE_NEW_CIRC', 'PATH_STATE_BUILD_ATTEMPTED', and 'PATH_STATE_ALREADY_COUNTED' not explicitly handled in switch [-Werror,-Wswitch-enum] switch (ocirc->path_state) { ``` I have a fix for this; just adding this ticket so I can give it a bug number.
