    Hi,
    there are both nonlinear equation solvers allowing bound constraints
    (for example NNES in http://plato.asu.edu/topics/probelms/zero.html)
    and general NLP solvers. In the latter I would not introduce a least
    squares objective because that softens the equations. I would either
    not have an objective at all if the solver accepts that or use f=0
    otherwise. For free NLP solvers in Fortran, see
    http://plato.asu.edu/topics/problems/nlores.html#general.
    both in the bound-constrained section and in the following sections
    (DONLP2 etc).
