------- Comment #30 from ubizjak at gmail dot com  2008-09-06 16:11 -------
Current mainline (4.4.0 20080906) produces:

        pushl   %ebx
        movl    8(%ebp), %eax
        movl    16(%ebp), %edx
        movl    20(%ebp), %ecx
        movl    12(%ebp), %ebx
        imull   %eax, %ecx
        imull   %edx, %ebx
        mull    %edx
        addl    %ebx, %ecx
        popl    %ebx
        leal    (%ecx,%edx), %edx

So, fixed.
