The docs are wrong now.  For compatibility with Matlab the comma is
now a command separator.

If you want to declare multiple global variables on one line, omit the
commas.

If you want your code to be Matlab compatible, don't use initializers
in the global statement.  Write

  global c d e
  c = 3;
  e = 5;

instead.
