The new de-facto LTS compiler is gcc 4.2.1, the last version released under GPLv2. After gcc switched to GPLv3, Apple and FreeBSD stayed on 4.2.1.

I'm not sure all of OpenBSD's platforms have code generation support in 4.2.1 - for example, the m88k issue given in the article.

But that is definitely a good place to stop/start (depending on how you look at it)

Apple no longer ships gcc at all.

4.2.1 is from 2007 and it hasn't been S'd for a LT by anybody.

FreeBSD moved to clang. I don't know for Apple.
