Thanks a lot for opening this thread!

It has been quite a pain for many D contributors as this target 
never received much love and thus is probably the one with the 
most "random" bugs in it and I remember quite a few times where 
contributors had to waste hours trying to workaround the 
auto-tester 32-bit OSX build as they couldn't reproduce the error 
locally.
Also, if we remove support for it, the OSX builds on the 
auto-tester will receive a doubled capacity.

So, as our resources and manpower are stretched thin, I think we 
should focus on targets that are actually being used and I 
suggest to drop support for it.
