Alright, so what do we need to do to test this?  We really just need a
short C program written up and then a bunch of folks to run it on
various architectures, right?  Gee, sounds like what the buildfarm was
made for (alright, alright, PostgreSQL isn't exactly a 'short C
program', but you get the idea).  As I recall, Andrew reworked the
buildfarm code to be more modular too..  Anyone have thoughts about how
we could run these kinds of tests with it?  Or do people think that's a
bad idea?
Thanks,
