+Current implementation of the pressure gradient... blablabla... 
+We modify the implementation of the pressure gradient according to A19 from NEMO book 4.0.1 :
+in dynhpg routines we compute the specific pressure gradient with the density anomaly : when possible we merely remove the znad, otherwise we remove explicitely the surface pressure gradient (dynhpg_prj, dynhpg_djc).
+in dynspg routines we compute the surface pressure gradient with constant density systematically
+
+Note that using a density anomaly only in dynhpg_isf, requires also changes in isfload and isfstp.
