It's:
jeremy@cosworth:~/hg/xen/paravirt/linux-x86_64$ gcc -v
Reading specs from /usr/lib/gcc/x86_64-linux/3.4.4/specs
Configured with: ../src/configure -v
--enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr
--libexecdir=/usr/lib --with-gxx-include-dir=/usr/include/c++/3.4
--enable-shared --with-system-zlib --enable-nls
--without-included-gettext --program-suffix=-3.4 --enable-__cxa_atexit
--enable-libstdcxx-allocator=mt --enable-clocale=gnu
--enable-libstdcxx-debug --enable-java-gc=boehm --enable-java-awt=gtk
--disable-werror x86_64-linux
Thread model: posix
gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13)

I think this is still a supported compiler, isn't it?
