That's about writing a new pass *as*a*plugin* - do you need to write a
new pass or write a plugin?

*Plusings* require GCC 4.5, new passes don't.

(But that's still not a reason to use GCC 4.5.0 instead of GCC 4.5.3!)

Are you asking if it's possible to write a plugin for 4.1.2 (that's
impossible) or possible to write a new pass?
