Implement non- standard function equivalent to stpcpy/stpncpy. * wcsmbs/wcscoll.c: Implement `wcscoll' function by using `strcoll' implementation. * wcsmbs/wcscpy.c, wcsmbs/wcsncpy.c: Use wint_t instead of wchar_t. * wcsmbs/wcstod.c: Implement `wcstod' function by using `strtod' implementation. * wcsmbs/wcstof.c: Same for `wcstof'. * wcsmbs/wcstold.c: Same for `strtold'. * wcsmbs/wcstol.c: Implement `wcstol' function by using `strtol' implementation. * wcsmbs/wcstoq.c: Same for `wcstoq'. * wcsmbs/wcstoul.c: Same for `wcstoul'. * wcsmbs/wcstouq.c: Same for `wcstouq'. * wcsmbs/wcswidth.c: Implement `wcswidth' function from X/Open CAE. * wcsmbs/wcwidth.c: Ditto for `wcwidth'. * wcsmbs/wcwidth.h: Common function for definitions of above two functions. * wcsmbs/wcsxfrm.c: Implement `wcsxfrm function by using `strxfrm implementation. * wctype/wctype.c: Remove case for `wctype_t' being 16 bit type. * wctype/wctype.h (wint_t): Protect against multiple definition. (wctype_t): Always define as `unsigned long int'. * wctype.h: New file. Wrapper around wctype/wctype.h. * hurd/hurdstartup.c (_hurd_split_args): Function removed.
