 * FIELD3 is the third field of the version number.
 * This is what we'd like FIELD3 to be:
 *
 * #define FIELD3 (PY_MICRO_VERSION*1000 + PY_RELEASE_LEVEL*10 + PY_RELEASE_SERIAL)
 *
 * but that neither gives an error nor comes anywhere close to working.
 *
 * For 2.4a0,
 * PY_MICRO_VERSION = 0
 * PY_RELEASE_LEVEL = 'alpha' = 0xa
 * PY_RELEASE_SERIAL = 0
 *
 * gives FIELD3 = 0*1000 + 10*10 + 0 = 100
