I see what you are trying to do, and I wonder if it would be possible for you to use the += construction instead: VARIABLE := default-value ifneq(condition) VARIABLE += additional-flags endif which needs less maintenance in the long run (for example, adding things to default-value requires changing a single line, not two). Thanks.
