Hi! When upgrading a gcc tree < r230888 with objdir to r230888 or later and just doing make in the gcc subdir, I'm getting errors - genmatch complains that it doesn't know IFN_FMAX. The problem seems to be a missing dependency, build/gencfn-macros depends on internal-fn.def and thus cfn-operators.pd is updated, but build/genmatch does not depend on it, even when it includes internal-fn.def, so has not been rebuilt and fails to parse the new cfn-operators.pd. Fixed thusly, ok for trunk?
