i'd be interested in your error output.  xfdesktop contains some Xlib 
stuff, so that could cause a problem (although, with cygwin/xfree86, i 
would think it should still compile).  at any rate, i don't have any 
interest in patching xfdesktop 4.0.x to compile under cygwin.  CVS HEAD 
would be nice, however.

i'm not quite sure why this is needed, since, IIRC, some of those 
libraries do contain unresolved symbols (at link time, anyway).  seems 
like adding -no-undefined would make it _not_ work.  then again, i don't 
always understand libtool all that well....

we're theoretically using 1.5.6 for everything, but the reality is 
really that most of us (myself included) don't have 1.5.6 installed on 
the machines on which we do our dev work.  when all our stuff is 
upgraded, i'd expect that it might work out-of-the-box.

if i were you, i wouldn't bother with the 4.0.x branch.  i'd bet that 
any changes that need to be made to add cygwin support would likely be a 
bit too intrusive for olivier's taste, seeing it's the stable branch.  
hell, i wouldn't feel too great about it, and we all know how much i 
like to b0rk things around here...  try checking out CVS HEAD.  it's 
pretty stable most of the time (i run it both at home and at work).  in 
that case, you should run instead of configure - this will 
pull in the required system libtool for you.
