* parser.l (YY_NO_UNPUT): Removed superfluous #define. This is not

needed because suppressing generation of unput is requested via
the %option. In scanners generated by the legacy version of
flex, 2.5.4, still widely in use. this redundancy leads to
a multiple #define YY_NO_UNPUT and a compiler warning.
