Hmm.  I wonder if "The Right Thing To Do" is to ensure that libjava's 
version of ltdl.c is uptodate -- that is, taken from libtool-1.5 and not 
1.4.x, and then rebuild libjava, the modules, etc.

Or rebuild libjava so that it uses the system-installed version of 
cygltdl-3.dll and not a self-compiled one.

Then, we'll at LEAST know that everything is speaking the same dlopen 
language.

Plus, can somebody do an strace on the program that fails to load the 
.la files?  And make sure that dlopen & friends ARE in fact being 
called, as they should be on the cygwin platform?  (That is, instead of 
asking for LoadLibrary workarounds, let's make sure that we're actually 
using -- and that the modules themselves are expecting -- the 
cygwin-provided, fork()-friendly dlopen stuff).
