cl.el redefines the `mod' function, which several levels down
calls signum.  In older versions of timer.el signum is a macro,
while in cl.el signum is a function.  Calling a macro as if it
were a function make Emacs unhappy.  The solution is to change
all references to signum in timer.el to timer-signum and
re-bytecompile timer.el.
