Perhaps Leopard's Xcode used to default to gcc 4.0 and then changed to 4.2 later and we didn't notice. I thought it was that "gcc" on the command line was gcc-4.0 while in Xcode projects gcc-4.2 was used by default, but I could be mistaken.

Frank expected whereis(1) to behave differently than it in fact does.
His 'port select' output shows that his 'gcc' is /opt/local/bin/gcc. On
Leopard, /usr/bin/{gcc,g++} are links to {gcc-4.0,g++-4.0}.
