See my comment inline in the code.

You cannot pass params in this way. With Layer.GML you must do:

gmlLayer = new OpenLayers.Layer.GML("villages",
    "http://localhost/cgi-bin/mapserv.exe?map=../htdocs/amap/sites_wfs.map&typename=villages&outputformat=gml2");

In addition, don't you miss the service, version and request params to
make it an actual WFS request?

gmlLayer = new OpenLayers.Layer.GML("villages", [
    "http://localhost/cgi-bin/mapserv.exe",
    "?map=../htdocs/amap/sites_wfs.map",
    "SERVICE=WFS",
    "VERSION=1.0.0",
    "REQUEST=GetFeature",
    "&typename=villages"
    "&outputformat=gml2"].join(",")
);

But I don't that will fix the getSize problem, which I currently don't
see where it comes from. Sorry.
