It overrides -m32 earlier on the command line. It's also possible to build 32-bit configurations which support 64-bit compilation - but the default i686-linux configuration does not. The i686-solaris2.10 port does, and Debian's i486-linux compilers do also (local patch). -- Daniel Jacobowitz CodeSourcery
