commit    0ade8421b5b2c85185fdfddbd5833222e5d4146b
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Wed Jun 22 17:08:08 2011 +0000
First released in: 9.2.0, 9.1.0

    Fix symlink for errcodes.h so it works in VPATH builds from tarballs.
    
    backend/Makefile was treating errcodes.h as a header always generated
    during build, but actually it's a header provided in tarballs.  Hence,
    must use the absolute-symlink recipe, not the relative-symlink one.
    Per bug #6072 from Hartmut Raschick.
