Generalized least squared model with known covariance matrix

I try to fit a GLS model in which the responses are correlated with a
knonw covariance matrix, hence I need to sandwich the covariance
matrix into the normal equation. Wonder how that can be done with the
existing procedures in Splus version 3.3 for Windows.
Thank you.
