Subject: Fix symlink for errcodes.h so it works in VPATH builds from tarballs.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0ade8421b5b2c85185fdfddbd5833222e5d4146b;p=pg-rex%2Fsyncrep.git

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.
