    Revert previous 2 commits, and instead conditionally redefine the same macro used in flex 2.5.35 that clashed with our workaround.
    
    Not surprisingly, the workaround was exactly the same code as was provided by
    the Flex maintainers, albeit in two different places, in different macros.
    
    This should fix the FreeBSD builds, which have an older version of Flex.
