 This is a followup on a concern reported by Stephane Carrez on the
 GDB mailing list:
 
     http://sources.redhat.com/ml/gdb/2003-02/msg00533.html

 I think we shouldn't fail like this because we have some symbols for an
 unsupported language. Could we for instance fallback to C for unknown
 language symbols.
 
 I looked at set_cu_language in dwarf2read.c. What would be the
 consequences of setting cu_language to language_c in these cases:
 
     case DW_LANG_Ada83:
     case DW_LANG_Ada95:
     case DW_LANG_Cobol74:
     case DW_LANG_Cobol85:
     case DW_LANG_Pascal83:
     case DW_LANG_Modula2:
     default:
       cu_language = language_unknown;
       break;
