# Sorry for this. I will look at my code and I try to figure out what might
# cause the problem. For the time being I do not have a clue. 
# The fact that I do not have 2.9.3 does not make it any easier.
# 
# I tested on 2.9.4 and did not incur any error-messages. The same for 2.1.72,
# provided you compile with -DNO_SPARSE and have some necessary prerequisites
# from octave-forge (dispatch.oct and isequal.m)

Ok, if it works w/ 2.9.4, don't worry about 2.9.3, I'll catch up @
some point, possibly soon. More news then.

  Thx,

  Etienne
