icecc preprocesses source files locally before shipping them off to be compiled
on remote hosts. This preprocessing removes comments, including /* fallthough */
comments in switch statements that normally prevent an implicit-fallthrough
warning, see https://github.com/icecc/icecream/issues/419
Rather than turning off -Werror, the upstream project has implemented a
configure option, --disable-werror, in response to Ross's
https://github.com/json-c/json-c/issues/489
