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.
