Just to give you an idea of the impact of the recent events:
g++ -I. libs/phoenix/test/core/primitives_tests.cpp -c
real 0m1.525s
user 0m1.370s
sys 0m0.137s
----------------------------------------------------------------------------
g++ -I. libs/phoenix/test/core/primitives_tests.cpp -c -
DBOOST_PROTO_DONT_USE_PREPROCESSED_FILES -
DBOOST_PHOENIX_DONT_USE_PREPROCESSED_FILES
real 0m2.626s
user 0m2.463s
sys 0m0.157s

g++ -I. libs/phoenix/test/core/primitives_tests.cpp -c -

This means that phoenix V3 is up to 50% faster than V2!
This is all depending on the usecase of course. Other testcase show that V3 is
either as fast to compile or a little faster!

I double that! Thanks!
