Can this annoyance be removed, please? Reading this bug thread, it seems that various options were suggested (mostly around different move-if-changed solutions), but they all seemed to have various problems. I think that it's unlikely that a user runs configure twice in a row without changing any options, so I don't personally see any problems with re-compiling all the .c files after running configure, so I wonder whether there's really anything to be done here. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
