  Modified files:
    contrib/libpcap      scanner.l 
  Log:
  When pcap_compile() detects an error, it longjmp()'s out of the
  scanner/parser. FreeBSD recently made 'flex' its default implementation
  of 'lex'. One of the incompatibilities of 'flex' vs. 'lex' is that
  if you longjmp() out of the scanner, you must call yyrestart()
  before doing another scan (as documented in flex(1)). So add an
  invocation to yyrestart() in lex_init(). This change should be
  backwards compatible with the original 'lex'.
