I simply thought that there was a "standard" way to do this: EViews and Stata 
both give the exact same F statistic for my original problem. Given that these 
programs were not developed by the same author (AFAIK), there is some specific 
way to reformulate the restriction which make EViews and Stata give the same 
answer.
