I tried adding this verbatim, and found that it didn't work at all (it
appeared to attach itself to the last rule defined, which in my case was
"clean").  So I removed the tabs, and it seemed to work, until I tried to
make a second time (that's always the big test).  I gave a big error then:
birth.d:1: *** multiple target patterns.  Stop.

I can't seem to figure it out, and I would really like this, since this is a
fairly large project and I'm compiling it fairly often.

Well, the makefile isn't that big-- here it is.  It's for Angband 2.7.9, by
the way.
