With covariancy THUNK_TARGET can itself be a thunk. Do you need an additional

How do you think should a testcase for that look like?
I have tried g++.dg/abi/covariant*.C and on none of the these

abi/covariant4.C contains such a case. In use_thunk it encounters such a condition (I think use_thunk handles it incorrectly, btw). I don't have a comdat-group supporting assembler - binutils 2.15 segfaults during the configure test. do you know what version is good on i86?
