Interesting question. I looked at the install instructions and there is
no mention of this for MSVC or BCC:

http://www.postgresql.org/docs/8.2/static/install-win32.html

I looked at the win32.mak file, and see no refererence to libpq.rc.in,
so how is the MSVC working? Should we add rules for both?

Uh, it is supposed to be build by this rule:

$(srcdir)/blibpqdll.def: exports.txt
echo '; DEF file for Borland C++ Builder' > $@
echo 'LIBRARY BLIBPQ' >> $@
echo 'EXPORTS' >> $@
sed -e '/^#/d' -e 's/^\(.* \)\([0-9][0-9]*\)/ _\1@ \2/' < $< >> $@
echo '' >> $@
echo '; Aliases for MS compatible names' >> $@
sed -e '/^#/d' -e 's/^\(.* \)\([0-9][0-9]*\)/ \1= _\1/' < $< | sed 's/ *$$//' >> $@

Is there a reason this failed?

Yes, I saw that. It is not clear whether this is a libpq problem or a
Wine problem. We are unsure how to debug this. I wonder whether it is
a problem with getaddrinfo. We did fix an addrinfo issue in 8.2.1:

* Improve handling of getaddrinfo() on AIX (Tom)

I wonder if that fixes it.
