This can be done with the flex "-P" option, but that changes yywrap(), too. Flex allows one to work around this by adding %option noyywrap. Note that e.g. Solaris' lex does not have -P. In the long run I believe the pcap library should implement this rather than every program using it. >Release-Note: >Audit-Trail: >Unformatted:
