Sascha Wildner has posted a patch that makes it very easy to switch out the compiler used to build DragonFly. This builds on earlier work from Alex Hornung.
This should make it into the base system. Everyone’s looking at compilers that aren’t gcc these days, it seems.
Besides the things that make PCC and Clang a good alternative (mainly easier debugging, tuning, etc.) it makes the BSDs more portable in an other way the the ‘usual’ platform porting.
This shows the BSDs are still following the Unix philosophy and therefor programmed by people, who know what they are doing.
From an other point of view you can say the creators of Unix and its philosophy made very good decisions and knew/know what they were/are talking about. I mean there are not many people saying something which stays valid for more than 30 years, especially not in the IT world.
