I have done a code like

try
{	if(_error)	throw "Error";}
catch(char *message)
{	cerr<<message<<endl;};

and compile it with the flag -fhandle-exception (?), it works fine.

There is a problem that you can not have an exception in a base class where the derived class has also an exception.
I have post this problem before, but the mail seems lost in the net.
