Find workaround for warnings at Dynare startup under Octave
When Dynare starts under Octave, one gets:
warning: function /home/sebastien/dynare/unstable/matlab/+pac/+bgp/get.m shadows a built-in function warning: called from dynun at line 4 column 5 warning: function /home/sebastien/dynare/unstable/matlab/+pac/+bgp/set.m shadows a built-in function warning: called from dynun at line 4 column 5
This is the consequence of an Octave bug.
A partial workaround was implemented in 4c0b2e8c, but it does not suppress early warnings.
A better solution should be found.
