           Summary: [7 regression] bootstrap fails for x86_64-darwin at
                    stage1 after 243030 when the bootstrap compiler
                    doesn't have strndup
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

         Component: bootstrap

The bootstrap compiler has a sysroot suitable for Darwin10 (which doesn't have
strndup, strnlen etc.)
