Bug #: 30973
           Summary: Unsupported symbol id warnings when backtracing with
                    Visual C 2010 .pdb files
           Product: Wine
           Version: 1.5.6

I built the tiny demo from bug 835 with Visual C 2010, and ran it under Wine.
Happily, Wine generated good backtraces still,
but there were several unsupported symbol id warnings, e.g.

fixme:dbghelp_msc:codeview_snarf Unsupported symbol id 113e
fixme:dbghelp_msc:dump 00000000: 1a 00 3e 11 08 10 00 00 01 00 45 78 63 65 70
74  ..>.......Except
fixme:dbghelp_msc:dump 00000010: 69 6f 6e 52 65 63 6f 72 64 00 00 00           
  ionRecord...    
fixme:dbghelp_msc:codeview_snarf Unsupported symbol id 1141
fixme:dbghelp_msc:dump 00000000: 0e 00 41 11 11 00 00 00 dc 16 00 00 01 00 27
00  ..A...........'.
fixme:dbghelp_msc:codeview_snarf Unsupported symbol id 1144
fixme:dbghelp_msc:dump 00000000: 06 00 44 11 08 00 00 00                       
  ..D.....

There are so many of these warnings that it's easy to miss the fact
that there's still a good stack trace.
