A simple solution is to filter such things in a pre-commit hook; here's an
example using unix shell syntax:

#!/bin/sh
REPO="$1"
TXN="$2"

if svnlook changed -t "$TXN" "$REPO" | grep ^A | grep ':'; then
  echo Files or directories with colons in their name are not permitted >&2
  echo due to windows interoperability concerns. >&2
  exit 1
fi

I don't know windows scripting syntax, but this should be easy enough to port
to whatever scripting languages you have available.
