FWIW: I've fixed a few upstream recipes that were doing this to use the
__attribute__((fallthrough)) instead of a comment.
Anyway, usually the correct fix is to add the package to
ICECC_SYSTEM_PACKAGE_BL in icecc.bbclass; it is maybe not ideal but
ICECC_DISABLED is the user control for enabling and disabling icecream
globally, not a per-recipe flag.
The current blacklist is woefully outdated, I really need to get around
to updating it

I struggled to find a solution that would work in the -native case, as
we need to support gcc as old as 5.4 (Ubuntu 16.04).
The problem is somewhat specific to json-c, as -Werror is hard-coded
into configure.ac in this package.

Considering the pain that the gcc upgrade introducing that warning
caused I'll be *very* surprised if this problem is limited to json-c.
Could the icecc class forcibly disable that warning instead?

icecc preprocesses source files locally before shipping them off to
be compiled
on remote hosts. This preprocessing removes comments, including /*
fallthrough */
comments in switch statements that normally prevent the
implicit-fallthrough
warning.
Rather than turning off -Werror by patching configure.ac, it is
simpler to
disable icecc completely for json-c. There are very few source files
to compile,
so the compilation is quick even without icecc.
