Dear Masa,
Thanks for your message and the fact that you made some time to look into
the problem.
I will try it out and will let you know.
However, my intention is to run my code under ROOT in batch via

root -b -q main.cc >main.log

How can I here specify optimization level 3 instead of 4 ?
I would prefer to be able in the .rootrc (or rootlogon.cc) to set the
optimization level. Is this possible ?

Cheers,
Nick.
