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. Add
LA_PRINT_TYPE and LA_VAL_PRINT macros. Change local_printchar
to LA_PRINT_CHAR and local_printstr to LA_PRINT_STRING.
* m2-lang.c (m2_create_fundamental_type): Remove unused local
variable nbytes.
* m2-lang.c (m2_language_defn): Add initializers m2_print_type
and m2_val_print.

* main.c (execute_command): Remove unused local variable cmdlines.
* main.c (echo_command), stabsread.c (read_type), printcmd.c
(clear_displays), symmisc.c (block_depth), values.c
(clear_value_history):
Make testing of truth value of assignment result explicit.
* mipsread.c (upgrade_type): Update FIXME to include future use
of create_range_type.
* printcmd.c (ptype_command, ptype_eval, whatis_command,
whatis_exp, maintenance_print_type): Move prototypes and functions
to new typeprint.c.
* printcmd.c (_initialize_printcmd): Move add_com calls for
ptype_command and whatis_command to new typeprint.c.

when LSEEK_NOT_LINEAR is defined.
* stabsread.c (read_array_type): Use new create_range_type
function.
* stabsread.c (read_range_type): Add new index_type variable and
call new create_range_type function rather than handcrafting
range types.
* symmisc.c (type_print_1): Change usages to LA_PRINT_TYPE.
* symtab.c (typedef_print usages): Use c_typedef_print, renamed.
* symtab.c (type_print_base usages): Use c_type_print_base.
* symtab.c (type_print_varspec_prefix usages): Use
c_type_print_varspec_prefix.
* symtab.c (type_print_method_args usages): Use
cp_type_print_method_args.
* valprint.c: Completely ripped apart and the fragments used
to create c-valprint.c, cp-valprint.c, m2-valprint.c, and
valprint.h. Remaining stuff is language independent.
* value.h (struct fn_field): Forward declare for prototypes.
* value.h (type_print_1): Remove prototype.

* 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.
