but this is easy to forget I think...
We have some ARG_ENABLE which then in case does some
CFLAGS="$CFLAGS -Werror"
(the name of the option depends on $CC of course) after
some (most?) checks.
I guess this also is wrong because CFLAGS shouldn't be set?
Also the order matters which isn't good either.
But how else?

Also I dislike that our macros that implement e.g. -Werror and friends have
to know all supported compilers and their switches. Is there a better way
to do that?

  (...maybe team mates that need -Werror [because otherwise check
   in warnings] tend not to use editors that parse make output... SCNR ;) )
