OK, thanks. Looking at the "simplest" model
(
https://gennaro.zezza.it/software/eviews/glch03.php [3]), there is no
econometrics involved, it is "just" about simulation. It would be
interesting to see whether the dynamic accounting relationships could
be specified in gretl's system block as (dynamic) identities. It's not
clear to me whether that is supported by gretl. (Also noting that the
doc in ch. 34 says that identities only matter for FIML estimation, so
another question is about their role in forecasting.)
Usually, SFC models are pure simulations. It's rather a recent trend
trying to estimate some of the model parameters.

Actually, while the first entry there is with R code, further down
you have Python codes and a Java-based toolkit (and also Mathematica,
but that is again closed source, of course).

Right. The relatively recent addition of lpsolve support (linear
programming) might also be relevant here. (See Help / gretl +
lpsolve).
I was also thinking of lpsolve for solving the (dynamic) system using
gretl.
