Nobody suggested using -pedantic, certainly I didn't.  That's a
completely useless option and I really would like for it to be removed.
 Just like -ansi.

First of all, warnings by the linker are not covered by -Werror.
Second, there are -Wno-* parameters which can and should be added after
the -Wall to avoid some warnings _for specific files_.  It's just a
matter of setting the Makefiles up to make this easily possible.  The
elfutils makefiles do just that.
