Wait, you're saying the ".file" directive is supposed to have an effect
in stabs?  I would have thought this would come from the first .stab
instead.

If so, then we need to change GCC to emit '.file "foo.c"' like other
ports do.  '.file 1 "foo.c"' is DWARF-2 usage, not STABS usage, and gas
has no business trying to second-guess the compiler.
