The message is complaining that sizeof(ConfigureNamesEnum) changed,

I guess because of this in guc_tables.h:
extern PGDLLIMPORT struct config_generic ConfigureNames[];
Evidently, but I don't see how that provides a sizeof() value to
onlookers. Just to be sure, I tried to compile a use of that,
and got
test.c:43:53: error: invalid application of ‘sizeof’ to incomplete type ‘struct
config_generic[]’
elog(NOTICE, "sizeof(ConfigureNames) = %zu", sizeof(ConfigureNames));

So if this isn't an outright bug, it's at least unhelpful behavior.
Fair enough. I agree it's not terribly helpful. In any case, maybe we
need to look at my earlier suggestion of adding a suppression file.
