I just downloaded snapshot 4.1-20051029 which reports the version that you
mentioned and it exhibits the same behavior:

./hello

Hello, world!

To compile the snapshot, I did this:
  mkdir /tmp/gccobj
  cd /tmp/gccobj
  mkdir ~/gcc4.1-20051029
  ~/tmp/gcc-4.1-20051029/configure --prefix=/home/davel/gcc4.1-20051029
--enable-languages=c,c++
  make bootstrap-lean
  make install
