OK that worked for 3.3.3 - I got a 1.8MB cyggmx-4.dll installed along 
with a working 600K mdrun. The catch is that this extra "-no-undefined" 
is an argument to libtool, rather than the underlying linker. You can 
use "./configure CFLAGS=blah LDFLAGS=blahblah" to pass things to the 
compiler and linker, but I don't know of technique to pass things to 
libtool without the editing you suggest. I'll see if I can figure 
something out, check it on 4.0.5 and wikify the outcome.
