Both of these were broken by:
2004-02-21  Ziemowit Laski  <zlaski@apple.com>

         * config/darwin.h (TARGET_OPTION_TRANSLATE_TABLE): Refer to
         SUBTARGET_OPTION_TRANSLATE_TABLE for architecture-specific 
options.
         * config/i386/darwin.h (SUBTARGET_OPTION_TRANSLATE_TABLE): 
Define it.
         * config/rs6000/altivec.h: #error out if '-maltivec' not 
specified.
         (vector, pixel, bool): #define to __vector, __pixel and __bool.
         (__un_args_eq, __bin_args_eq, __tern_args_eq): Move to 
C-specific
         portion of header.
         (__altivec_link_error_invalid_argument): Remove prototype; will 
use
         __builtin_altivec_compiletime_error("vec_*") instead.
         (vec_*): Fix/complete set of available operation overloads 
given the
         existence of distinct 'vector bool ...' and 'vector pixel' 
types; tighten
         cv-correctness of pointer arguments; in C, always check for 
correct
         argument types before macro expansion.
         * config/rs6000/darwin.h (SUBTARGET_OPTION_TRANSLATE_TABLE): 
New macro
         defining Darwin/PowerPC-specific '-f[no-]altivec' and
         '-W[no-]altivec-long-deprecated' switches.
         * config/rs6000/rs6000-c (rs6000_cpu_cpp_builtins): Pre-define
         '__vector', '__pixel' and '__bool' macros using
         '__attribute__((altivec(...)))' types.
         * config/rs6000/rs6000.c (bool_char_type_node, 
bool_short_type_node,
         bool_int_type_node, pixel_type_node, bool_V16QI_type_node,
         bool_V8HI_type_node, bool_V4SI_type_node, pixel_V8HI_type_node):
         New type nodes.
         (rs6000_warn_altivec_long, rs6000_warn_altivec_long_switch): 
New, for
         handling '-W[no-]altivec-long-deprecated'.
         (rs6000_override_options): Handle 
'-W[no-]altivec-long-deprecated'.
         (rs6000_expand_binop_builtin, rs6000_expand_ternop_builtin,
         altivec_expand_dst_builtin): Remove casts from integer literals.
         (altivec_expand_builtin): Likewise; handle expansion of new
         '__builtin_altivec_compiletime_error' function.
         (rs6000_init_builtins): Initialize 'vector bool ...' and 
'vector pixel'
         types, and make them distinct from other vector types; register
         '__builtin_altivec_compiletime_error' function.
         (print_operand): For 'P', print a full target register name 
instead of
         merely its number.
         (rs6000_attribute_table): Add "altivec" attribute.
         (rs6000_handle_altivec_attribute): New function.
         * config/rs6000/rs6000.h (TARGET_OPTIONS): Describe
         '-m[no-]-warn-altivec-long' (which 
'-W[no-]altivec-long-deprecated'
         maps to).
         (rs6000_warn_altivec_long, rs6000_warn_altivec_long_switch): 
Forward
         declare.
         (ALTIVEC_BUILTIN_COMPILETIME_ERROR): New built-in enumeration.
