/* On most systems symlink() always creates links with rwxrwxrwx
protection modes, but on some (HP/UX 8.07; I think maybe DEC's OSF
on MIPS too) symlink() uses the value of umask, so links' protection modes
aren't always rwxrwxrwx. There doesn't seem to be any way to change
the modes of a link (no system call like, say, lchmod() ), it seems
the only way to set the modes right is to set umask before calling
symlink(). */
