But faster and likely easier to do once in source.

Any guess when gcc 4.5/5.0 might become available?
It's in stage 1 now.  Mid 2010 or so?

4.4.0 was April 21, 2009
4.3.0 was March 5, 2008
4.2.0 was May 13, 2007

Could you please send me what you think is a
reasonable .config for an embedded box.

cheers, Joe
