LPX_K_ROUND and LPX_K_RELAX are deprecated and kept in the glpk header
only for backward compatibility.

LPX_K_ROUND affected only lpx_print_sol. Now glp_print_sol uses a default
value sufficient in most cases.

LPX_K_RELAX allowed to choose the ratio test option. In the new api it
is equivalent to the control parameter glp_smcp.r_test.
