What to recompile when moving to a new version of gcc?

When changing your default version of gcc are there any general guidelines for what you should recompile to ensure you don't have any linking or runtime incompatibilities? I've run into issues before, sometimes needing to recompile kdelibs, but as I have not tested all software on my system I can't know what is potentially broken. What does fix_libtool_files.sh actually solve?

How much to recompile depends on how much of a version change is made. Did you keep the same standard C library? Normally things should all work together as long as the ABI isn't changed. One approach is to recompile when something is found not to work. The other approach is to recompile everything.
