This seems like it would allow multiple versioned functions from
different namespaces; I want to allow mismatches only if they are
versions of the same function. I was thinking
for (match = TREE_CHAIN (matches); match; match = TREE_CHAIN
(match))
if (!decls_match (fn, TREE_PURPOSE (match))
&& !targetm.target_option.function_versions (fn,
TREE_PURPOSE (match)))
break;

Let's just say "use of multiversioned function without a default".
