8. Switching System GCC(Optional) Finally, to easy Managing GCC Versions use Alternatives 
 So now to Set System for to manage a Multi Compiler.
 First, possibly disable the existing Target with:sudo mv /usr/local/bin/gcc /usr/local/bin/gcc.bak Then to Add the New GCC with alternatives use: sudo alternatives --install /usr/local/bin/gcc gcc /usr/bin/x86_64-redhat-linux-gcc 20 Again Add the System GCC: sudo alternatives --install /usr/local/bin/gcc gcc /usr/bin/gcc 10 (The Setup is working if as of default /usr/local/bin is preceding /usr/bin on the $PATH Env Var) 
 Next to Switch between GCC Versions play:sudo alternatives --config gcc Last, to test the GCC in use: gcc -v 
 
Congratulations, your GCC 13.2 should be now nicely working on Fedora 38. Good Luck! :)
