where necessary to the main trunk (0.9.8-dev). This does not include rearrangements and work I've been doing, that'll come in the next bunch of commits to this branch. This set of changes can't be expected to work on any VMS system, there are changes in here that are very specific to Compaq's building system. This set of changes will be surrounded by the tags BEFORE_COMPAQ_PATCH and AFTER_COMPAQ_PATCH.
