That's what mozilla does. We have a --with-static-checking configure flag,
and our annotations (NS_FINAL_CLASS etc) are defined conditionally. We have
to do that anyway since we compile with MSVC and SunCC and other compilers.
You could use -Wno-attributes, which suppresses warnings about *all* unknown
attributes. Alternately, we could modify GCC so that -Wno-attributes takes
an optional argument, e.g.
-Wno-attributes=user
-Wno-attributes=NS_stack
--BDS
