This isn't probably good idea. After all I still want to develop programs
which would use only Cxx features where xx < 99 using DragonFlyBSD. Fixing
system compiler would be acceptable.

There is comment #1 in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24012
which explains how it's dealt in Linux - _GNU_SOURCE is defined all the
Anyway, at the moment I'm thinking that unless we just fix the bug in
