Gotta love this argument. If what you're saying has any real ground, it just
means Postgres source structure and build process sucks beyond anything I've
seen before. It SHOULD BE possible to logically prove that addition of new
platform does not break others. If not, you've got yourself problem without
my patch.

At this point, I suggest core developers will ask me when/if they feel like
they want another submission from me.

Merry X-mas & happy new year everyone.
