* Makefile.in (VERSION): Bump to 4.7.4.

Change function body to use passed in range_type rather than handcrafting one. * gdbtypes.h (create_range_type): Add prototype. * gdbtypes.h (create_array_type): Change prototype parameters. * infrun.c (normal_stop): Remove unused local variables tem and c. * infrun.c (hook_stop_stub): Return 0 rather than random value. * language.c (unk_lang_print_type, unk_lang_val_print): Add stub functions that call error if called. * language.c (unknown_language_defn, auto_language_defn, local_language_defn): Add initializers unk_lang_print_type and unk_lang_val_print. * language.h (struct language_defn): Reformat for larger comments, add la_print_type and la_val_print members.

Remaining stuff is language independent. * value.h (struct fn_field): Forward declare for prototypes. * value.h (type_print_1): Remove prototype. * value.h (enum val_prettyprint): Moved to defs.h. * value.h (typedef_print): Prototype renamed to c_typedef_print. * value.h (baseclass_offset): Add prototype. **** start-sanitize-chill **** * Makefile.in (SFILES_MAINDIR): Add ch-typeprint.c, ch-valprint.c. * Makefile.in (OBS): Add ch-typeprint.o, ch-valprint.o. * ch-typeprint.c: New file for language dependent type printing. * ch-valprint.c: New file for language dependent value printing. * ch-exp.y (parse_number): Remove prototype and stub function. * ch-exp.y (decode_integer_literal): Removed unused digits and temp variables. * ch-exp.y (convert_float): Completely ifdef out for now. * ch-exp.y (tokentab2, tokentab3, tokentab4, tokentab5), ch-lang.c (chill_op_print_tab): Change from ANSI-obsolescent "const static" to ANSI-conformant "static const". * ch-exp.y (yylex): Add unhandled storage class enumeration literals to switch statement for completeness. * ch-lang.c (chill_create_fundamental_types): Remove unused nbytes variable. Change dummy type to 2 bytes to match int. Handle FT_VOID types gratuituously added to chill DWARF by compiler. Change FT_CHAR case to generate an TYPE_CODE_CHAR type rather than a one byte TYPE_CODE_INT type. * ch-lang.c (chill_language_defn): Add chill_print_type and chill_val_print. * ch-lang.h (chill_print_type, chill_val_print): Add prototypes. **** end-sanitize-chill ****
