I have a pending patch for this at http://mail.gnu.org/pipermail/automake-patches/2002-May/000823.html Basically, it just replaces the `y.tab.h: y.tab.c' dependency by y.tab.h: y.tab.c if test ! -f $@; then \ rm -f y.tab.c; \ $(MAKE) y.tab.c; \ fi (Automake does something similar in the handling of config.h already.) What do you think? Would this be enough for you? [...] -- Alexandre Duret-Lutz
