Smart move... you don't want "make install" to rm the previous compiler then find a problem with the new one. Trust me on this... Easiest way is to add a prefix to some alternative install location, e.g. --prefix=/opt/experiment/gcc to the configure command and rebuild. Then "make install" will install to /opt/experiment/gcc instead of the default. (You may need to create the /opt/experiment/gcc folder, and run "make install" with permissions to write to it) Then before you test, you add /opt/experiment/gcc/bin to $PATH, e.g. export PATH=/opt/experiment/gcc/bin:$PATH - Brian
