Subject: The AngleArc() function that was being used to draw circles on Windows turns
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=a0d0c7e795268068642a315227a8e2f754d6968a;p=sgt-puzzles.git

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).
