This can be fixed routinely. I hesitate to create patch though since there are a lot of declarations in bfin-aux.h. It's possible to fix the place we get warnings.

I don't think so. It seems gcc-3.4 is stricter than gcc-4.x on shadow warning. gcc-4.x does not report these warnings.
-Wshadow was just added to cvs binutils ...
$ cat t.c int foo; int bar (int foo);
$ gcc-3.4 -S -Wshadow t.c t.c:2: warning: declaration of 'foo' shadows a global declaration t.c:1: warning: shadowed declaration is here $
$ gcc-4.4 -S -Wshadow t.c $
