If you have access to the web server you can check the logs (with 
Apache, it would be the access.log that would contain the request)
You can also get it in your browser by checking the URL referenced by 
the image.

As I understand it, Openlayers (at least version 2.7) does not support 
wms 1.3.0. But you can still do the following and use CRS:84 in your case:

var options2 = {
             maxExtent: new OpenLayers.Bounds(-180, -90, 180, 90),
             units: 'degree',
             //projection: "EPSG:4326"
             projection: "CRS:84"
            };
             map = new OpenLayers.Map( 'map', options2 );
             layer = new OpenLayers.Layer.WMS( "gmap wms",
 
"http://127.0.0.1:8080/cgi-bin/mapserv.exe?map=f:/msapps/gmap-ms40/htdocs/gmap75_wms_4326.map", 
{layers: 'DEMO', VERSION:'1.3.0', EXCEPTIONS:'INIMAGE', CRS:'CRS:84'} );
             map.addLayer(layer);

I think QGIS does support wms 1.3.0. At the end what the GetMap 
parameters should be is:
  ...&CRS=EPSG:4326&BBOX=ymin,xmin,ymax,xmax  or
  ...&CRS=CRS:84&BBOX=xmin,ymin,xmax,ymax
