I need to translate this (it should read the same timer used by Win API 
QueryPerformanceCount):

    unsigned short val;
    cli
    xor al,al
    out 43h,al
    in  al,40h
    mov bl,al
    in  al,40h
    mov bh,al
    mov [val],bx
    sti
    return val;

into AT&T syntax (for DJGPP). I wrote this:
asm(
  "cli\n\t"
    "xor %al,%al\n\t"
    "out %al,$0x43\n\t"
    "in  $0x40,%al\n\t"
    "mov %al,%bl\n\t"
    "in  $0x40,%al\n\t"
    "mov %al,%bh\n\t"
    "mov %bx,$val\n\t"
    "sti"
);
but I get: "Assembler messages: 20: Error: suffix or operands invalid for 
`mov'".
Please, could somebody help me?

Thanks
Cristiano
