Performance, for(int i...) vs for(i...)

[lab@kayohamid.net]

Hello, I like performance, and until last month i follow what I see on 
the web to do better coding for performance, like:

- Avoid i++, use ++i and so on.

But now i'm using the assembly (-S) code generated to see if somethings 
is correct, and today i'm investigating this:

int i;
for(i = 0;....);

vs

for(int i = 0;...);

I make 2 codes:

----
int main()
{
int i;
for(i = 0; i < 10; i++) {}
}

----

int main()
{
for(int i=0;i<10;i++) {}
}

----

the result of forin.c and forout.c is the same:

         .file   "forin.c"
         .text
         .globl  main
         .type   main, @function
main:
.LFB0:
         .cfi_startproc
         pushl   %ebp
         .cfi_def_cfa_offset 8
         .cfi_offset 5, -8
         movl    %esp, %ebp
         .cfi_def_cfa_register 5
         subl    $16, %esp
         movl    $0, -4(%ebp)
         jmp     .L2
.L3:
         addl    $1, -4(%ebp)
.L2:
         cmpl    $9, -4(%ebp)
         jle     .L3
         movl    $0, %eax
         leave
         .cfi_restore 5
         .cfi_def_cfa 4, 4
         ret
         .cfi_endproc
.LFE0:
         .size   main, .-main
         .ident  "GCC: (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3"
         .section        .note.GNU-stack,"",@progbits

Seeing this, can I say that using int inside the for or outside for is 
the same? Have no difference on performance?
