GCC permits not only unnamed structs and unions, but cv-qualified ones. Our earlier fix in 6c3a38777b38a2ad87e2b2bcec4567578d1c83ec supported unnamed structs and unions, but only unqualified ones. Resolving away cvr-quals of nameless fields (and, irrelevantly, typedefs) is easy and fixes this problem. Tests adjusted accordingly. libctf/ PR libctf/32746 * ctf-types.c (ctf_member_next): Resolve away cv-quals. (ctf_member_info): Likewise. * testsuite/libctf-lookup/struct-iteration-ctf.c: Add a cv-qualified type or two: make sure to keep a non-qualified one. * testsuite/libctf-lookup/struct-iteration.c: Verify consistency of ctf_member_next and ctf_member_info. * testsuite/libctf-lookup/struct-iteration.lk: Adjust.
