* Versions.def (libc): Add GLIBC_2.2.6. * hurd/Versions (libc: GLIBC_2.2.6): Add __errno_location. * sysdeps/mach/hurd/errnos.awk: In generated macro, use __errno_location instead of __hurd_errno_location, and don't inline it. * sysdeps/mach/hurd/bits/errno.h: Regenerated. * hurd/errno.c: New file. * hurd/Makefile (routines): Add errno.
