Thanks Tom, that was it. An old libpq-int.h was compiled into a precompiled
header.

The reason I'm using libpq-int.h is that I can use SELECT-ed data from
not-yet-complete queries, and this is very useful for long searches which
yeld data from time to time. The only other approach I can think of, cursor
open / fetch, causes bidirectional network traffic and it's not very
efficient when there are many immediate results. OFC I understand that using
internal libpq stuff means I'm on my own, so I was thinking will you accept a
patch which would allow libpq provide data from incomplete queries ? I've
asked about this before, your statement was that this breaks the consistency,
but sometimes it doesn't really matter, e.g. with searches.
