-statsby- seems to work for me:
. use http://www.stata-press.com/data/r9/labor.dta,clear
. mark wc if we>12
. statsby, by(cit) clear:treatreg ww wa , treat(wc=wmed ) twostep
(running treatreg on estimation sample)
command: treatreg ww wa, treat(wc=wmed ) twostep
by: cit
Statsby groups

In your original formulation:
-treatreg y a b c if d==`i', treat(c= l m n) twostep-
^^^
This c variable will be dropped since it is the treatment equation.
What error message do you receive with the -forv- loop?
