AREA bug msg

http://www.weather.gov/ptwc/ doesn't work because it uses real numbers
rather than integers for coords. The 4.01 spec doesn't quite _rigorously_
state that real numbers are no good in that case, so far as I can see,
but it's pretty clearly the intention -- and html5 _does_ spell this out.
