Subject: The AngleArc() function that was being used to draw circles on Windows turns
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/84cf18f701885475a025e3350492bbffcc201113

The AngleArc() function that was being used to draw circles on Windows turns
out to be unsupported on the Win9x/Me series. Use Arc() instead (tested on
Win98 and Win2K).
