I participate in projects which have _seriously_ broken dependencies. In these cases, I do a quick "touch source.c" to force a recompilation. You'd break this workaround. Ciao, Dscho P.S.: yes, I know I could possibly find the object file and remove that, too. But finding the source is often easier.
