With 'cs2cs' (provided by PROJ4) it should be:
LATLONG/ED50 -> Gauss-boaga Ovest/Roma40

cat coordsED50.txt | cs2cs +init=epsg:4230 +to +init=epsg:26591 \
      +towgs84=-85.88,-28.85,+49.67,-1.003,-2.383,-1.808,-27.82 > coordsGB1.txt

Fuso Est:
 Gauss-boaga Est is +to +init=epsg:26592

Be sure to pick the right (local) towgs84 parameters.

Hope this helps,

 Markus
