Here's a proposal: how about I add a --add-stdcall-alias to dlltool which
essentially produce the following:

      EXPORTS
      Java_HelloWorld_displayHelloWorld=Java_HelloWorld_displayHelloWorld AT 8
      Java_HelloWorld_displayHelloWorld AT 8

When creating .def file using ``dlltool --output-def''. Would this solve 
the problem? Note that I'm keeping the original symbol as well, but we 
could always get rid of that too.

Making DLLs then look like the following:
  
  dlltool --output-def my.def --add-stdcall-alias [ ... ] *.o
  dllwrap -o my.dll --def my.def [ .... ]*.o

btw, you should *never* export DLL entry points (unless you really know
what you're doing of course).
