* io/Makefile (routines): Add euidaccess.
* sysdeps/mach/hurd/euidaccess.c: New file. * sysdeps/stub/euidaccess.c: New file. * posix/unistd.h [__USE_GNU] (euidaccess): Declare it. * dirent/Makefile (routines): Add dirfd. * sysdeps/stub/dirfd.c: New file. * sysdeps/unix/dirfd.c: New file. * sysdeps/unix/dirstream.h (_DIR_dirfd): New macro. * dirent/dirent.h (dirfd): Declare new function. Define as macro _DIR_dirfd if that is defined. * sysdeps/mach/hurd/dirstream.h (DIR): Replace `__port' member with `void *__fd'. * sysdeps/mach/hurd/opendir.c: Use DIRP->__fd instead of DIRP->__port. Open the file with `open'; set FD_CLOEXEC on the fd. * sysdeps/mach/hurd/closedir.c: Likewise. * sysdeps/mach/hurd/readdir.c: Likewise. * sysdeps/mach/hurd/dirfd.c: New file. * posix/Makefile (glob/configure): Do cvs commit if there is a CVS directory.
