[Limdep Nlogit List] OLS constraints

I have a simple theoretical OLS model of the following form:

Y = a + b*x1 + c*x2

According to the theory, the estimated coefficients of this model should 
be constrained as follows:

c = a - b

I have tried to program this model in Limdep in several different ways, 
including the CLS command, but it does not seem to want to cooperate.

Is there a problem in constraining the intercept term?

Please advise. Thanks!
