How to Enable C++ Exceptions

 I would like to enable C++ exceptions in CCS for the 'C6455. Is this possible? I have not found any means to do this in the project build options. 
 I'm using CCS release 3.3.82.13. 

I'm porting a large project from Visual Studio 2008 which makes exceptional use of exceptions, thus I would prefer not to rewrite a large volume of code if possible......

The compiler error is: " support for exception handling is disabled"
The offending code is: throw constraintError(lineNum,this_file,(const char*)buf);

Thanks,

Peter
