I do not pass any option to gcc.

$ gcc --version
gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2

The script I use to compile the vm:

$ cd /tmp && svn co http://squeakvm.org/svn/squeak/trunk squeak-svn &&
cd squeak-svn && mkdir bld && cd bld &&
../platforms/unix/config/configure --prefix=/opt/squeak && make &&
sudo make install
