I think what both of you don't realize is that the cases where the C
front end checks for DECL_SOURCE_LINE == 0 are *all* (to the best of
my knowledge) dealing with declarations synthesized by the Objective
C front end, for which *neither* DECL_BUILT_IN nor DECL_ARTIFICIAL
evaluates true.  (I might be wrong about DECL_ARTIFICIAL, but even
if I am, I'd be leery of changing the test, because DECL_ARTIFICIAL
is used for other stuff too.)
