Coordinate System transform failed for some Projection CS

[liuar]

It's a defect in Proj4js.

For example:

Transform to EPSG:4326 from following wkt, the result is always NaN

PROJCS["HARN/WI.SheboyganWI-M",GEOGCS["HARN/WI.LL",DATUM["HARN/WI",SPHEROID["GRS1980",6378137.000,298.25722210],TOWGS84[0.0000,0.0000,0.0000,0.000000,0.000000,0.000000,0.00000000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse Mercator, Wisconsin County Variation"],PARAMETER["false_easting",79857.760],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",1.000000000000],PARAMETER["central_meridian",-87.55000000000000],PARAMETER["latitude_of_origin",43.26666666670000],PARAMETER["Average Geoid Height (meters)",-34.0200],PARAMETER["Average Elevation (system unit)",182.8800],UNIT["Meter",1.00000000000000]]
