Subject: Can't unroll loops when using "-O" Optimation and having defined labels 
 with asm

I have defined labels in my asm-code within a loop, but cannot use the
"unrool-loops switch"  in combination with the "O"-Optimation.
Everytime I try this, I get the following error:
"Fatal Error:  Symbol XXX already defined"         (Where XXX is my
label)
This also happens when I write the correct (I think so) but nonsense
code:

unsigned short x;
for (x=0;x<8;x++)
{
asm("jmp end\n\t"
       "end:\n\t");
}
How can I avoid this ?
Even the "volatile" command after asm did not help !
