Description 

In each case where a label was angled incorrectly, it was angled incorrect by
roughly +- 180°.

Versions 4.6.2 is affected as well as the CVS head (feb. 24, 2006).

The problem is with ANGLE AUTO. More precisely in msPolylineLabelPoint() in
mapprimititve.c:

if(p->line[i].point[j-1].y < p->line[i].point[j].y){ 
    *angle = (270.0 - (MS_RAD_TO_DEG*theta));
    // *angle = (90.0 - (MS_RAD_TO_DEG*theta));<-----------------BEFORE (WRONG)

}else{
    *angle = -(270.0 - (MS_RAD_TO_DEG*theta));
    //*angle = -(90.0 - (MS_RAD_TO_DEG*theta));<-----------------BEFORE (WRONG)
