If you have no additional control variables than you have a fully saturated model and there is no problem with using the code for continuous data with the addition of the -vce(robust)- option. See: <http://www.stata.com/statalist/archive/2012-02/msg00351.html> If you have additional control variables you need to be a bit more careful and do some more checking to see if the model is reasonable, but in many cases I would suspect that the linear probability model will still be just fine.
