I did a quick test of the developers sources and octave-3.2.3. For each, the 
global attribute was preserved. Perhaps an upgrade to a newer version will 
resolve the problem for you?

Variables in the current scope:

  Attr Name        Size                     Bytes  Class
  ==== ====        ====                     =====  ===== 
    g  a           1x1                          8  double
       b           1x1                          8  double

Total is 2 elements using 16 bytes
