Summary: Loop turns negative when it shouldn't

Initial Comment:
void main( void )
{
   unsigned char *adr;
   unsigned char buf[ 16 ];
   unsigned char i;

   adr=0xA000;
   for ( i = 0; i < 16; i++ )
   {
      buf[i]=*adr;
      ++adr;
   }
}

Actually is compiled as if the for loop reads:
   for (i=16; i>0; --i)
Which copies values from adr to buf the wrong way 
around. Rewriting buf[i] to *(buf+i) solves it.

I'm using the MingW september 8 snapshot.
Compiler flags: -mz80 -c
