The dyngen targets still require gcc3 to build, OTOH making qemu more
portable is valuable. I believe the policy should be "avoid compiler
extensions unless it is hard to do without".

This idea is IMHO of dubious value. It obfuscates the control flow, and
it wouldn't work for a plugin system (where self-containedness would be
the biggest win).
