what will get backported?

[Jack Howarth]

Jerry,
   Actually I am far more concerned about changes where optimization
improvements are being made by wiring in the backend optimizers to
gfortran. Specifically thing like...

http://gcc.gnu.org/ml/fortran/2006-03/msg00174.html

which result in significant perform increases in the generated code
while not actually implementing new features or touching things outside
of the gfortran code. I would really hate to see those sort of things
put off until gcc 4.2.
