I considered this again and again, and while I understand the
unfortunate situation you ran into with the old system compiler
on older versions of your OS, I am tempted to side with Richard
-- and GCC plugins really make (more) sense with reasonably
current versions of GCC, so by identifying GCC 4.5 we might
set wrong expectations.
