3.9-4 VM on cygwin: check that /usr/local/lib/squeak/3.9-4/vm-display-X11.so exists

[Klaus D. Witzel]

Last night Squeak woke up running on the cygwin platform,

$ ./squeak.exe ../Squeak3.9b-7032.image 2>squeak.exe.log
displayModule 0x497170 null
soundModule   0x4970f0 null

(of course it currently has no io, so, who knows? :-)

Linked the vm-display-null and vm-sound-null modules together with vm.a,  
by tweaking sqUnixMain.c and its makefile. Other vm-display-* and  
vm-sound-* modules are not so easy to harness, for example vm-display-X11  
(see messages below).

Next step is the -dlopen flag, for passing
*** Warning: libtool could not satisfy all declared inter-library
*** dependencies of module vm-display-X11.  Therefore, libtool will create
*** a static module, that should work as long as the dlopening
*** application is linked with the -dlopen flag.
