The following solution popped up in my head: compile the object twice, one time with -DPD_FLOATSIZE=32 and another time with -DPD_FLOATSIZE=64, with different setup functions based on -DPD_FLOATSIZE, then link it with a third file which exports the "real" setup function (which calls the other two private setup functions).
