open source way: use GRASS. when importing shapefiles with the v.in.ogr
command topology is automatically checked and you can clean as well
"other" way: try converting to a coverage and then use the "clean" and
"build" utilities in Arc, and then convert back to shp. just a guess
Note: I see that you also sent this to the PostGIS email list.
Cross-posting is bad-mojo. You should have probably sent this question
just to the PostGIS list (since it has nothing to do with MS4W).
