use restrict everywhere it's required by c99 and/or posix 2008 to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict. 2012-09-06 22:44:55 -04:00			`wchar_t wcsncat(wchar_t restrict d, const wchar_t *restrict s, size_t n)`

fix strncat and wcsncat (double null termination) also modify wcsncpy to use the same loop logic 2011-05-22 21:58:43 -04:00			`while (n && s) n--, d++ = *s++;`
