Below is an example ROOT session with v2.21/08 for Linux
compiled with KCC. After a gROOT->Reset(), ROOT/CINT apparently
does not know about cout, but neither will it reload iostream.h,
so I can't seem to get cout back to do basic I/O. Any suggestions
for how to keep cout even after a gROOT->Reset()?
Thanks.
Stephen
