Ports with modern compilers

[Dmitry Sarkisov]

Hello list,

I'd like to try building my ports with features and optimizations modern complers provide.
A couple of q. here:

1. What's the safest (less painful) way to go - build with fresh gcc or clang/llvm?
2. Is it ok to build new ports with new compiler, while already having a bunch of them build with default gcc version 4.2.1?

TIA
