The one-band extended Hubbard model in two dimensions near band-filling (1)/(2) is solved in the fluctuation exchange approximation, including the long-range ( 1/r) part of the Coulomb interaction, up to 4th-neighbor distance. Our results suggest that d_x2\ensuremath-y2 pairing in the Hubbard model is robust against the inclusion of long-range Coulomb interactions with moderate 1st-neighbor repulsion strength V1. d_x2\ensuremath-y2 pairing is suppressed only at large V1 ( \ensuremath\gtrsim0.25U--0.4U), due to incipient charge density wave instabilities.
