I've tripped over this myself but only when trying to do an incremental rebuild under conditions where an incremental build won't work. I do not know what those conditions are: I only know that blowing away the build tree and starting over from scratch has, until now, cured the problem. Are you seeing this in a build from scratch, not overriding subdirs? zw
