It looks to me like everything would work (assuming dlopen works), 
provided the libjava linked against the Cygwin libltdl instead of the 
one it subsumes from itself.  The problem in the libjava/libltldl in 
Cygwin's GCC 3.3.1-3 source distribution is that the HAVE_LIBDL code is 
disabled with a special case for Cygwin in order to supress some 
spurious error message. And unfortunately the fallback to LoadLibrary 
doesn't happen either because _WIN32 is not set.

While it would be good to update GCC at some point, this idea of getting 
GCC to take Cygwin's libltldl would seem to be the most flexible thing 
to have happen... (Assuming there are othher important reasons for 
having that libtldl DLL.)
