So how can we be sure all C compilers implement this switch? In
bsd.port.mk I see some traces of ICC support. Using this approach it
would also be possible to remap certain C standards to different
compilers.

Really, I really don't care how it's done, whether it's a flag or added
to the compiler flags directly. I'm just saying adding it to CFLAGS
directly sounds like a very bad idea. Adding it to /etc/make.conf sounds
even worse, because it probably only confuses (autoconf) scripts that
try to figure out a way to make the compiler speak C99.
