Googling around got me this:

Which, this patch fixes:

Though perhaps the check should be more modular?

TBBLe on IRC:
<TBBle>The probably correct procedure is either: "Check for a symbol in
-lXdmcp, if found, set a flag. If not, clear that flag, and throw #ifdef around
the code that uses Xdmcp" or "Check for a symbol in -lXdmcp, if not found, bomb
out of configure because we rely on Xdmcp for something intrinsic to what we're
doing".

With that patch (along with the other OpenBSD bugs patched around), and a
similar one for freetype (another bug in a sec), 'wine notepad' starts :-).
