I've changed gcc/configure.ac to use > AM_PATH_PYTHON and AM_CONDITIONAL: > > # Python3? > AM_PATH_PYTHON(,, [:]) > AM_CONDITIONAL([HAVE_PYTHON], [test "$PYTHON" != :]) But wouldn't this pick up a version of python < 3.0 if nothing else is present? If the python code inside gcc/m2 does require 3.x, shouldn't this be AM_PATH_PYTHON([3.0],, [:]) (or whatever is the minimum) instead?
