Yes, you're right. Sorry about that mistake.

Reading the code, I see that's not the logic. In rxvt/W11/wrap/wrap.c,
XOpenDisplay() does:
_libname="libW11";
when DISPLAY is unset or set to ":0", otherwise it does:
_libname="libX11";
Then _libname is used to generate the name of a library passed to
LoadLibrary(). I'm seeing this after my make completes:
bash$ strings -a src/rxvt.exe | grep libW11
bash$
Because the code in wrap.c is never linked into rxvt.exe, it doesn't
even know about libW11.dll, and it always uses
/usr/X11R6/bin/libX11.dll!
I made this patch to rxvt/src/Makefile and got a working non-X version
of rxvt.exe:
--- src/Makefile.orig 2003-05-03 20:41:30.000000000 -0400
+++ src/Makefile 2003-05-03 20:56:22.000000000 -0400

LDFLAGS =
DEFS = -DHAVE_CONFIG_H
-LIBS =

DINCLUDE =

but I'm not sure that's the right way to solve it, because the resulting
rxvt.exe still requires that libX11.dll is in my PATH, even though it
properly loads libW11.dll.
Am I missing something obvious, or is the failure to link against
W11/lib/libX11.a really the heart of the problem?
If so, why don't the Cygwin developers run into this problem? Perhaps
the rxvt source tarball I downloaded using setup.exe does not match the
CVS sources?
