You're not going to have a lot of luck building PG for those four
architectures from a single build run --- you really need a different
pg_config.h for each case. The specific failure you're seeing seems
to stem from SIZEOF_DATUM not agreeing with sizeof(Datum), but you
can bet your bottom dollar that that's just the tip of the iceberg.

I'd be somewhat interested to see a build approach that supports this,
but I don't want to spend any of my own time on it. I have a vague
suspicion that Apple probably built PHP four separate times and then
melded the executables after the fact.
