Is there any reason to not use this instead?
#undef YY_NO_UNPUT
#define YY_NO_UNPUT



It's supposed to be defined by the first line "%option nounput"
If anything, the line "#undef YY_NO_UNPUT" should be deleted, however Nick wanted to stick with this method in case someone has a broken implementation of lex.

He's the one that committed the ldlex.l change on March 28.
