with __warning__/__error__ attributes. (__warnattr): Define. * stdlib/bits/stdlib.h (__realpath_chk_warn, __ptsname_r_chk_warn, __mbstowcs_chk_warn, __wcstombs_chk_warn): New aliases with __warnattr. (realpath, ptsname_r, mbstowcs, wcstombs): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. * libio/bits/stdio2.h (__fgets_chk_warn, __fread_chk_warn, __fgets_unlocked_chk_warn, __fread_unlocked_chk_warn): New aliases with __warnattr. (fgets, fread, fgets_unlocked, fread_unlocked): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. (__gets_alias): Rename to... (__gets_warn): ... this. Add __warnattr. (gets): Call __gets_warn instead of __gets_alias. * socket/bits/socket2.h (__recv_chk_warn, __recvfrom_chk_warn): New aliases with __warnattr. (recv, recvfrom): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. * posix/bits/unistd.h (__read_chk_warn, __pread_chk_warn, __pread64_chk_warn, __readlink_chk_warn, __readlinkat_chk_warn, __getcwd_chk_warn, __confstr_chk_warn, __getgroups_chk_warn, __ttyname_r_chk_warn, __getlogin_r_chk_warn, __gethostname_chk_warn, __getdomainname_chk_warn): New aliases with __warnattr.

For constant __n fix check whether to use __*_chk or not. (fgetws, fgetws_unlocked): Divide __bos by sizeof (wchar_t), both in comparisons which function should be called and in __*_chk* arguments. Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. (swprintf, vswprintf): Divide __bos by sizeof (wchar_t) in __*_chk argument. * debug/tst-chk1.c (do_test): Add a few more tests.
