The NEWS file contains this item:

  * Commas in global statements are no longer special.  They are now
    treated as command separators.  This removes a conflict in the
    grammar and is consistent with the way Matlab behaves.  The
    variable `warn_comma_in_global_decl' has been eliminated.

So, if you want to declare more than one global variable in a global
statement, don't separate the variable names with commas.  Use

  global a b c d e;

instead of

  global a, b, c, d, e;
