Re: [HACKERS] index fix report

OK, it looks like there is a missing file in the tree. I had to modify

  ./backend/optimizer/prep/Makefile

to remove a reference to a nonexistant object file prepkeyset.o
presumably needing to be built from prepkeyset.c.

That got things building until the next link step, when some routines
were a missin'. Got that file anywhere? Seems useful...
