Yasm follows NASM behavior on this.  If BITS is 16, it uses cx by default, 
if BITS is 32 it uses ecx (and BITS=64, rcx).  To force use of ecx it's 
"LOOP label, ECX".

I suppose I could add a warning option to enable a warning for this.

It's offtopic, but duplicate identical function prototypes shouldn't be an 
error on any C compiler, although GCC might have an option for a warning 
on it.  (I believe the ANSI C standard says it's okay.)  Assembly, on the 
other hand, has no standard, so it's very assembler-specific on what's 
allowed where.

It looks like NASM has a -E option to specify an alternative file to 
output errors to.  I'll add support for this in Yasm.

Thanks,
