Would it work to #define vec_step to vec_step_ or something on affected hosts, say in system.h? I'd prefer that to renmaing since "vec_step" does seem the most natural name for the variable. The equivalent scalar variable is "step" and other vector values in the surrounding code also use the "vec_" prefix. Thanks, Richard
