Yes, thanks for pointing that out.  The F15 g++ accepts this translation
unit with -std=c++0x:

    enum x : int;
    enum x a;

This generates:

 <1><1d>: Abbrev Number: 2 (DW_TAG_enumeration_type)
    <1e>   DW_AT_name        : x        
    <20>   DW_AT_declaration : 1        
    <21>   DW_AT_byte_size   : 4        
    <22>   DW_AT_decl_file   : 1        
    <23>   DW_AT_decl_line   : 1        


I am going withdraw this patch and look at other ways to fix this
problem.
