# Python version constants
#
# It's better to evaluate these at runtime (i.e. C compile time) using
#
#      if PY_MAJOR_VERSION >= 3:
#           do_stuff_in_Py3_0_and_later()
#      if PY_VERSION_HEX >= 0x02070000:
#           do_stuff_in_Py2_7_and_later()
#
# than using the IF/DEF statements, which are evaluated at Cython
# compile time.  This will keep your C code portable.
