I failed to notice this comment, sorry.

Yeah, I think I had changed most places, but there will
be places I didn't, mainly to avoid growing the patch too
much with not-that-useful churn.  Here, we have:

static int
gdbscm_print_insn_from_port (struct gdbarch *gdbarch,
			     SCM port, ULONGEST offset, CORE_ADDR memaddr,
			     string_file *stream, int *branch_delay_insns)
{
  struct disassemble_info di;
  int length;
  struct gdbscm_disasm_data data;

  di = gdb_disassemble_info (gdbarch, stream);

and the only use of "stream" in the function is passing
the pointer to gdb_disassemble_info, so I left it be.

grepping the diff for "string_file \*", I get:

+                            string_file *stream, int *branch_delay_insns)
+string_file *
+  return (string_file *) m_streams.back ();
+  string_file *mi_stream = main_stream ();
+  struct string_file *stream = new string_file ();
+  string_file *main_stream ();

Looks like it may have been the only place.

Thanks,
