bug#11415: 24.1.50; Dbus hangs indefinitely during batch mode & daemon startup

[Paul Eggert]

That patch had a minor issue with it, discovered by configuring with
"./configure --enable-gcc-warnings", in that it sometimes resulted
in a local variable that was never used.  I installed the following
further patch to work around this.  These days there's no point to
making such variables 'register' so I removed the 'register' while
I was at it.
