It was the wrong theory anyway --- it already is included (in
Makefile.shlib). But what it does is provide -lpostgres on platforms
where that is needed, such as mingw.

Yeah. On closer investigation the problem seems to be -DBUILDING_DLL,
which flips the meaning of PGDLLIMPORT. contrib/dblink, which surely
works and has the same linkage requirements as walreceiver, does *not*
use that. I've committed a patch to change that, we'll soon see if it
works...

Yeah, nothing to be done till we get another buildfarm cycle anyway.
