Bug#422569: gcj-4.1: gcj debug info emits "line 0"

[Daniel Jacobowitz <dan@debian.org>]

Package: gcj-4.1
Version: 4.1.2-4
Severity: normal

I recently upgraded gcj (and/or ecj?) and now a couple of GDB tests fail.
To see the problem, take this file:

public class jmain
{
  public static void main (String[] args)
    {
	return;
    }
}

drow@caradoc:/space/fsf/commit/src/gdb% gcj -g -c -o j testsuite/gdb.java/jmain.java
drow@caradoc:/space/fsf/commit/src/gdb% readelf -wi j | grep decl_line
  <9c>     DW_AT_decl_line   : 0
  <b8>     DW_AT_decl_line   : 0
  <d7>     DW_AT_decl_line   : 0
  <13a>     DW_AT_decl_line   : 1
  <19f>     DW_AT_decl_line   : 5

Main appears to be declared on line 0 in the debug info.  That last
one is the argument "args".

I'm told this does not happen on GCC HEAD and I don't recall it
happening on earlier 4.1.x Debian packages either.
