This is pretty special, but i am ready to bet that you have seen the problem
only in gfs/gfs_fsck and gfs2/fsck and I am now able to reproduce this by
issuing twice in a row:
make clean all

I am going to investigate it, but I would like to know if there is a special
reason why we use -MMD and -include for *.d files (that are actually leaked in
the above command and hence the world fall apart in an endless blackhole).


I'm going to make him an offer he can't refuse.
