I don't see -Wno-unused-function above. I only see =
-Wno-unused-parameter.
I also don't see -Wno-parentheses-equality nor -Wno-conversion, so I
guess that means that the set of flags applicable for WARNS=3D3 isn't =
being
taken.

It looks like WARNS is in fact 3:
eris% make -V WARNS
3

Since bsd.sys.mk has grown unreadable, try unraveling the conditionals
to see if WARNS for GCC does the equivalent for CLANG. Is the problem
specific to architectures that don't use CLANG?
