I've been asking for help on the cygwin-xfree list also, with no luck yet:

I haven't yet sent them the gdb transcript.  I have a feeling that 
there's actually a very simple fix, but I don't know where to look.

Is it possible that this problem is related to the libXp library?  When 
texlive is built under X11R6.99, libXp gets pulled in.  Here's a line 
from build.log under X11R6.99:

	checking for XpQueryVersion in -lXp... yes

whereas the answer is "no" when I build texlive under X11R7.4.  (libXp 
provides the obsolete Xprint extension, which no longer exists in the 
newer X11.)  The effect of this is that the compilation of xdvi passes 
-lXp to gcc under the old X11 but not under the new one.  Does xdvi 
require libXp?  If so, I would have expected the configuration to quit 
with an error after not finding it.
