The version of flex that I have disallows the %a %p, ... directives needed
when I use lex. I would like to have a lex files which will work for both
systems. Does anyone have any neat way of conditionally including them or
any other hints about how to get flex to turn a blind eye to them.

Apart from yywrap (needs undefing if defined) what other problems might I
have with flex/lex compatibility.
