Your answer basically confirms what LHF said before. And I understand this. And I also agree regarding the unwise part. It's just that I made this mistake, and someone else (didn't look up that message in the archive) did that as well last week. 
So that is twice for just an RC. Breaking the build would not harm anyone, but might benefit some.

I updated my Windows build script [1] yesterday to now include the 5.2 specific one when building 5.3, mimicking the default make file behaviour. So I won't be doing that again :)
