I think that if Flex puts the lexer function into the namespace,  
Bison should do likewise, in view of the policy that Bison should be  
synced with Flex. If there are no C name conflicts, there should be  
no in C++, as the C++ namespace construct is essentially a language  
formalization of the C name-space programming technique.
