osm2pgsql February 2013 version not working on windows

I downloaded new osm2pgsql version (February 6, 2013) and i can’t make it work on windows. It shows “illegal option --w” on execute. I use the following (which allways worked with previous versions)

“osm2pgsql -c -d osm -s -S C:\sw\osm2postgre\default.style -U postgres -W -H localhost -P 5432 c:\mapas\spain.osm.bz2”

Thank you
