Subject: Optimization and Inline ASM

Dear DJGPPers,

I am puzzled at this error:
c:/djgpp/tmp\cccaaaaa: Assembler messages:
c:/djgpp/tmp\cccaaaaa:66: Fatal error:Symbol loc1 already defined.

This error only occurs if I use the optimize switch:

gcc myfile.cpp -O3

Compiles flawlessly if I use just:
gcc myfile.cpp

The code giving me the problem is:

void myproc()
{
  __asm__ __volatile__("
        cli\n
        movw $0x3DA, %dx\n
loc1:\n
        inb  %dx, %al\n
        andb $8,  %al\n
        jnz loc1\n
loc2:\n
        inb  %dx, %al\n
        andb $8, %al\n
        jz loc2\n");
}

What am I doing wrong? Help me, or I'll be bold soon! This error has driven
me NUTS!!!
