I have observed the same problem myself. It is not language dependent. At some point (perhaps when subdirectory builds were introduced) Automake diverged from using common rules, and started to insert per-target rules. It seems that a bit more smarts can be used to get close to automake 1.4 efficiency. Per-subdirectory rules and definitions can be added in order to significantly reduce the amount of redundant code, and to re-enable the capability to usefully override parts of the default Makefile.in. > One idea we had for a fix is to introduce a new "gnu-make" option that > would allow automake to generate code relying on GNU make. Then we > could replace all those rules with a single "%.o: %.java". This doesn't seem to be necessary.
