if you really want to be adventurous, try frename-registers, fpeel-loops, fweb 
or ftree-vectorize. Or ftracer. But don't complain, if something does not 
built (I have a set of save flags, just to be able to build freeciv. With my 
stupid standard flags, gcc will ICE)

maybe. When I switched from gcc3 to gcc4 I had to -e world.. and from the 
hundreds of packages 14 broke. 10 of them package.masked.

The problem: people with problems are very vocal, while the users without 
probs are silent.

So will see always lots of complaints, but almost never success stories.

I have not any more problems with my ~amd64 system than I had with my ~x86 
system. I would even postulate, that I have seen less breakage on ~amd64.
