I think it's good to keep compiler recent - bugfixes, optimization, features...
E.g. gcc 4.x can find some potential bugs in code and throw a warning while 3.x not for same code. In all my projects (my code, not just a ports) I use to have strictly 0 warnings so it's then more easy to detect a problem when warning rise instead of searching through hundreds of warnings that nobody reads anyway... But I'm also a bit conservative so I keep gcc 4.8.4 as main compiler. Also I found that 5.x produce bigger code.
