I'm going to post a new patch with a consistency check against . We could benefit from type information in glibcelf that is currently missing from , I think, so synthesizing from directly isn't quite possible. I'm not sure yet how regular the mappings are, e.g. if we use any of the *_HP_* constants (specific to HP/UX) for our parisc port. Maybe once this is sorted out, we can come up with a common ancestor as a data source. Thanks, Florian
