Subject: 	* flags.h (enum debug_info_type): Remove DWARF_DEBUG. 	*
 defaults.h (PREFERRED_DEBUGGING_TYPE): Remove check for 
 DWARF_DEBUGGING_INFO from choice-of-definition chain; 	restructure using C89
 features (#elif, #error). 	* c-lex.c, final.c, opts.c,
 config/cris/cris.c, config/frv/frv.c 	* config/sh/sh.h: Remove references to
 DWARF_DEBUG. 	* doc/invoke.texi: Remove references to DWARF version 1; 
 clarify why -gdwarf-2<n> doesn't work. cp: 	* class.c, search.c: Remove
 references to DWARF_DEBUG.
