I use the ROOT package with Geant. I recently upgraded to Geant4.4.0
and now I can't compile my Geant MC anymore. I get the
following error:

Compiling DefineHists.cc ...

It looks like a ROOT error, but it isn't. The program compiles without
any problems using geant4.3.2.

This really slows my work down, since I don't know where the change happened.

Please, help.

Thanks.
