…s. Note that the changes here are to the MOM_ice_shelf_dynamics.F90 function 'quad_area', which is only called by the subroutine 'bilinear_shape_functions'; this subroutine is currently unused so that rotationally-consistent use of FMAs in both 'quad_area' and 'bilinear_shape_functions' has not been tested

These changes all look correct to me, and I agree with them.
It should be noted that the mathematically equivalent changes on lines 3361 to 3364 of MOM_ice_shelf_dynamics.F90 are likely to change answers for cases that use a dynamic ice sheet, regardless of whether FMAs are being used.
