functionality adds recognition of '_' and "pl" as pseudonyms for '.', so that 1.2p2 == 1.2.2, and adds recognition of "pl" and "rc" strings, which stand for "patchlevel" and "release candidate" respectively. In addition, this version should handle alphabetic characters properly (so that 1.2e == 1.2.5) Normal NetBSD revision number processing has been retained (and is always compared after all other tests have been performed). 64-bit integers are used internally for each component of the version number.
