I suppose it depends on what one means by "work". My own suggestion would be for Autoconf to reject a "lex" implementation that does not implement yyless correctly, as apparently was the case with flex 2.5.4. The intent of that section of Autoconf, as far as I can tell (Akim hasn't weighed in), is to check that an acceptable version of "lex" is available. Any fix in this area would be fairly low priority, I would think. flex 2.5.4 dates back to when? 1997? And flex 2.5.31 has been out since 2003. As a general rule, lex and yacc should be invoked only by installers who have modified the source code; we can expect these guys to be a bit more up-to-date than usual.
