It is an error, and here's why:
digdug (atari), in galaga.c, depends on EAROM to store highscores/etc
the EAROM handlers are in atari_vg.o
hence galaga.c needs to depend on atari_vg.o

What probably SHOULD be done is split EAROM handling out of atari_vg.c and put it into /machine/earom.c or something
