I tried C++ compiler gpp yesterday ... but the problem is, that this
compiler will generate a load of overhead which I don't need. Thats gpp
output:

___gnu_compiled_cplusplus:
.text
 .p2align 2
.globl _main
_main:
LFB1:
 pushl %ebp
LCFI0:
 movl %esp,%ebp
LCFI1:
 xorl %eax,%eax
 jmp L2
 .p2align 4,,7
L2:
 movl %ebp,%esp
 popl %ebp
 ret
LFE1:

 .section .eh_frame
___FRAME_BEGIN__:
 .long LLCIE1

  .byte 0xd

 .p2align 2,0
LEFDE1:

that's gcc output:
