37 * Note: It would be nice to simply use the compiler-provided __FOO_TYPE__
38 * macros. However, in order to do so we have to check that those match the
39 * previous typedefs exactly (not just that they have the same size) since any
40 * change would be an ABI break. For example, changing `long` to `long long`
41 * results in different C++ name mangling.

157 * it looks like 10646 will be a 31 bit standard.  This means that if your
158 * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
159 * chosen over a long is that the is*() and to*() routines take ints (says
160 * ANSI C), but they use __ct_rune_t instead of int.
161 *
162 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
163 * be instantiated outside of lib/libc/locale.  Use wchar_t.  wint_t and
164 * rune_t must be the same type.  Also, wint_t should be able to hold all
165 * members of the largest character set plus one extra value (WEOF), and
166 * must be at least 16 bits.
