With check-c++-all RUNTESTFLAGS='--target_board=unix/-Wconversion' I managed to get a few extras: gcc/testsuite/g++.dg/cpp0x/initlist64.C (nofn) struct Y * vs. struct X gcc/testsuite/g++.dg/cpp0x/initlist64.C (nofn) struct Z * vs. struct X gcc/testsuite/g++.dg/cpp1y/context-conv1.C f struct zero_init * vs. int * gcc/gcc/testsuite/g++.old-deja/g++.benjamin/16077.C foo struct nicaragua * vs. struct colombia gcc/testsuite/g++.old-deja/g++.mike/p807.C main struct AX * vs. struct B gcc/testsuite/g++.old-deja/g++.other/overcnv2.C main struct B * vs. const char *
