Yeah, 2.5.33 is fine (in fact it's what I installed on my HPUX box to
replace 2.5.4).  AFAICS OSX 10.5 is fine, but 10.4 will need a newer
flex version.  This is not anything very new to Mac users.  10.4 also
shipped with bison 1.28, which is too old to build Postgres and has been
too old for many years now.  So anyone building from CVS on that
platform has already installed at least one nondefault tool.

(For comparison's sake: flex 2.5.4 was released in 1996.  2.5.31, which
I'm proposing to make the new minimum, was released in 2003.  Bison
1.875, our current minimum for that tool, was released in 2002, and
we made it the minimum required version in 2003.)
