* csu/Versions: Use %include <tls.h> to get USE_TLS defined.
(libc: GLIBC_2.0) [USE_TLS && HAVE___THREAD]: Remove _errno, errno. (libc: GLIBC_2.3) [USE_TLS && HAVE___THREAD]: Put errno here instead. * resolv/Versions: Use %include <tls.h> to get USE_TLS defined. (libc: GLIBC_2.0) [USE_TLS && HAVE___THREAD]: Remove _h_errno, h_errno, and _res. (libc: GLIBC_2.3) [USE_TLS && HAVE___THREAD]: Put h_errno, _res here. * elf/tls-macros.h [__x86_64__] (TLS_LE, TLS_IE, TLS_LD, TLS_GD): New macros for x86-64. * sysdeps/unix/sysv/linux/alpha/bits/time.h: File removed. It was indentical to the linux/bits/time.h file. * nscd/nscd_gethst_r.c (nscd_gethst_r): Add a cast to silence warning. * resolv/gethnamaddr.c (gethostbyaddr): Use socklen_t for SIZE.
