I have actual bad experience with this :)
v4 of this patch series excluded 'compat/' from the conversion, but
the semantic patch is applied to 'compat/' all the same, resulting in
failed CI builds because of the four 'extern's in 'compat/obstack.h',
and will continue to do so.
(Coccinelle has no issues with those other header files; I guess those
are not included in the '.c' source files we analyze with Coccinelle
in a stock Linux build environment).
