Unfortunately, you need to preserve the line numbers of these messages unless
you want to check in a new reference build for the performance tests that are
still based on the AutomationProxy framework.

Is it okay to put the new preprocessor conditionals in the existing empty lines
between messages to preserve line numbering?

I noticed that a new message was inserted in r176470. I don't see a
corresponding commit to the reference builds. Is there a reason that an update
wasn't needed in that case?
