  3. + Fixed: On certain systems running CygWin, a call to socket functions + like gethostname() could cause deal.II to hang. The reason seems to be that the call disables long double computations which revert to just double precision. This then leads to an endless loop in computing weights for quadrature points because the convergence criterion cannot be reached with simple double precision. This is now fixed by disabling the call to gethostname() on these - systems. + systems.
