Although I did not look exhaustively to the errors, I have found three classes:

(1) gcc.target/i386/builtin_target.c fails with
Undefined symbols:
  "___cpu_indicator_init", referenced from:
      _main in cckJG3Id.o

(2) For gcc.dg/darwin-cfstring-1.c, the errors have changed from

/opt/gcc/work/gcc/testsuite/gcc.dg/darwin-cfstring-1.c

(3) The ICEs I have looked at are of the kind
