c++: designator and anon struct [PR101767]
We found .x in the anonymous struct, but then didn't find .y there; we
should decide that means we're done with the struct rather than that the
code is wrong.
PR c++/101767
gcc/cp/ChangeLog:
* decl.cc (reshape_init_class): Back out of anon struct
if a designator doesn't match.
gcc/testsuite/ChangeLog:
* g++.dg/ext/anon-struct10.C: New test.
