>GCC 5

A bit surprising for a BSD project, seeing as 4.2.1 was the last GPLv2-licensed release and most of the rest of the BSD communities seem, shall we say, not too enthusiastic about GPLv3.

NetBSD also isn't bothered much the GPLv3 change of gcc, NetBSD 7 will ship with gcc 4.8

Its more a case of wanting to use two compilers and GCC is the other choice after clang.

DragonFly has always had more of an emphasis on user-friendliness than the others.
