As the others have already said, gcc-config is the way to switch between |
14 |
gcc versions. In theory, every time you switch between different gcc's |
15 |
you *should* run 'fix_libtool_files.sh <old-gcc-version-number>' *and* |
16 |
recompile every package that links to libstdc++ (because libstdc++ is |
17 |
part of the gcc package and gcc-config switches versions of libstdc++). |

I suspect most people don't actually do those things, however :) |
