+json-c: Backport --disable-werror patch to allow compilation under icecc
+
+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
+
+This patch from
+https://github.com/json-c/json-c/commit/21c886534f8927fdc0fb5f8647394f3e0e0874b8
