I've rebased this again.

I also moved away from using hash tables for storing references and
libraries. I was having some problems getting psql to compile due to
the order of the dependencies being reversed due to the order being at
the mercy of Perl's hash function. There's mention of this in
Makefile.global.in:

# libpq_pgport is for use by client executables (not libraries) that use libpq.
# We force clients to pull symbols from the non-shared libraries libpgport
# and libpgcommon rather than pulling some libpgport symbols from libpq just
# because libpq uses those functions too. This makes applications less
# dependent on changes in libpq's usage of pgport (on platforms where we
# don't have symbol export control for libpq). To do this we link to
# pgport before libpq. This does cause duplicate -lpgport's to appear
# on client link lines, since that also appears in $(LIBS).
# libpq_pgport_shlib is the same idea, but for use in client shared libraries.

I switched these back to arrays but added an additional check to only
add new items to the array if we don't already have an element with
the same value.

I've attached the diffs in the *.vcxproj files between patched and unpatched.
