c-common.c (builtin_define_type_precision): New function.
gcc/
2002-08-28 Gabriel Dos Reis <gdr@integrable-solutions.net>
* c-common.c (builtin_define_type_precision): New function.
(cb_register_builtins): Use it. Define __WCHAR_UNSIGNED__ is
wchar_t is unsigned in C++.
* doc/cpp.texi (Common Predefined Macros): Document
__WCHAR_UNSIGNED__, __CHAR_BIT__, __WCHAR_BIT__, __SHRT_BIT__,
__INT_BIT__, __LONG_BIT__, __LONG_LONG_BIT__, __FLOAT_BIT__,
__DOUBLE_BIT__, __LONG_DOUBLE_BIT__.

* include/std/std_limits.h (__glibcpp_char_bits,
__glibcpp_short_bits, __glibcpp_int_bits,
__glibcpp_long_bits,
__glibcpp_long_long_bits, __glibcpp_float_bits,
__glibcpp_double_bits, __glibcpp_long_double_bits):
Remove. Use
compiler predifined macros.
(__glibcpp_wchar_t_is_signed): Define based on compiler
predefined
__WCHAR_UNSIGNED__.
