Yes, it clearly has. But I tend to think that that's far outweighed by the
complications triggered by AIX support. It'd be a different story if AIX
hadn't a very peculiar linking model and was more widely accessible.

Hm.
- a distinct set of system libraries that can help find portability issues
- With IBM's compiler it adds a, not otherwise used, compiler that PG builds
with. So the warnings could theoretically help find issues that we wouldn't
otherwise see - but I don't think that's been particularly useful (nor
monitored). And the compiler is buggy enough to add a fair bit work over the
years.

Right.
