        .type   main, @function
main:
        lea     %ecx, [%esp+4]
        and     %esp, -16
        push    DWORD PTR [%ecx-4]
        push    %ebp
        mov     %ebp, %esp
        push    %ecx
        mov     %eax, 0
        pop     %ecx
        pop     %ebp
        lea     %esp, [%ecx-4]

        .ident  "GCC: (GNU) 4.1.1"
        .section        .note.GNU-stack,"",@progbits

These register names are plain not-intel like.

I was able to reproduce it on:
GCC: (GNU) 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

If I'm not wrong somewhere - this is a bug. Hope it'll be easy to fix or is
even fixed in experimental versions - I have no way to test that.
