[maplab-users] LatLongBoundingBox problem with WFS server

Hello,
I'm trying to use MapServer as a WFS server, pulling data from a PostGIS
DB. My original data is not projected, it's in geographic coordinates
(lat/long) in the NAD83 datum. When I use the GET method to issue a
'getcapabilities' request it displays the XML file, but I get weird
bounding box coordinates :
<LatLongBoundingBox minx="-2.5e+007" miny="-2.5e+007" maxx="2.5e+007"
maxy="2.5e+007"/>
The extent defined in my MAP file is -69.2 45.0 -33.2 48.2 (in decimal
degrees). When I try to open the WFS layer in uDig, I can't see
anything, uDig seems to be confused by the wrong numbers in
LatLongBoundingBox (when I'm moving the mouse around in the map window,
it displays out of bound coordinates). On the other hand, when I issue a
'getfeature' request from a web browser, I get the right numbers for the
<gml:coordinates> tags :
<gml:coordinates>-69.588602,44.311578 -62.161745,48.794835</gml:coordinates>
Here is my MAP file :
