[Click] Compilation problems redux

[Eddie Kohler]

Hi Bob,

I think the problem is related to your specification of CC and CXX on  
the ./configure command line.  Click's configuration system generally  
adds the following options to $CXX: "-W -Wall -fno-exceptions  
-fno-rtti".  But if the user gives explicit CC/CXX it doesn't do this;  
it expects the user to do so if necessary.  So, could you please try to  
reconfigure with "CXX='whatever -fno-exceptions -fno-rtti'" and let us  
know what happens?

Eddie
