Hi, The problem here is that the typedef overrides the previous type. To avoid that, we have to check that the new DECL is not a type. Some code uses supplement_binding to 'refine' the binding, so if the new DECL is a type and is of the same type than the old binding, then supplement_binding succeeds.
Bootstrapped, regtested on x86_64-unknown-linux-gnu.
OK for trunk ?

* name-lookup.c (supplement_binding_1): If the old binding was a
type name, also check that the DECL actually refers to the same
type or is not a type.
