 As discussed in the proj bug tracker a while ago
 ([http://trac.osgeo.org/proj/ticket/47
 http://trac.osgeo.org/proj/ticket/47]), there was a problem with the
 definition of datum transformation parameters for EPSG 31370 in the proj
 epsg file.

 The same issue is still present in QGIS' srs.db, leading to a slight
 offset of 10-20m. Running:


 {{{
 update tbl_srs set parameters='+proj=lcc +lat_1=51.16666723333333
 +lat_2=49.8333339 +lat_0=90 +lon_0=4.367486666666666 +x_0=150000.013
 +y_0=5400088.438 +ellps=intl
 +towgs84=-106.869,52.2978,-103.724,0.33657,-0.456955,1.84218,1 +units=m
 +no_defs' where srid='31370';
 }}}


 Solves the problem for me.
