GNATS setup problem [MAILER-DAEMON@sourceware.cygnus.com: failure notice]

[Daniel Jacobowitz]

I was under the impression that one just had to CC: gcc-gnats and keep
the PR in the subject line in order to add to a PR.  What am I missing?

Also, something is obviously unconfigured.

 For the curious, this is the exact same problem as c/4053.

 Well, it isn't in the debug format code; the file information in the
 RTL is wrong.  And there's nothing obviously incorrect about the code
 in cb_file_change...
 
 Aha, I think I see it.  cb_file_change updates input_filename as it
 reads.  Compile the testcase from the PR with a breakpoint on
 cb_file_change and a breakpoint on emit_line_note.  If I had to guess,
 I'd say that the problem was input_filename describing the state of the
 lexer where it used to describe the state of the parser.  In
 c_expand_body is the line:
   init_function_start (fndecl, input_filename, DECL_SOURCE_LINE (fndecl));
 
 DECL_SOURCE_LINE is fine.  input_filename isn't.
