Cannot link Java native libs on Win32 with MinGW [patch]

Hello,

still going on with all my problems with MinGW...

Now the biggest one with no complete solution, cos JRex does not start 
XPCOM.

In the native Makefile.in we have :

ifeq ($(OS_ARCH),WINNT)
EXTRA_DSO_LDOPTS+= \
        $(JAVA_HOME)/lib/$(LIB_PREFIX)jawt.$(LIB_SUFFIX) \
        $(JAVA_HOME)/lib/$(LIB_PREFIX)jvm.$(LIB_SUFFIX) \
        $(NULL)

But on Win32 Java native libs does not have a "lib" prefix, as have C++ 
libs...
For this problem I propose to write (and it is the attached patch) :

ifeq ($(OS_ARCH),WINNT)
EXTRA_DSO_LDOPTS+= \
        $(JAVA_HOME)/lib/jawt.$(LIB_SUFFIX) \
        $(JAVA_HOME)/lib/jvm.$(LIB_SUFFIX) \
        $(NULL)

Now the strange consequence : the linker is going on with the jawt lib 
but it cannot link the jvm lib (this two libs are in the same 
directory.?.?.).
I found another strange behaviour with libs on Win32 here 
[http://www.mozdev.org/pipermail/jrex/2005-February/001476.html], but 
this solution does not seem to work for me.

My problem is identified on the Sun Developper Network there 
[http://forum.java.sun.com/thread.jspa?threadID=596522&messageID=3925672], 
but the solution is for MS Visual Studio.
Same problem there 
[http://www.velocityreviews.com/forums/t150203-error-invoking-jvm-through-jni.html] 
with a proposal for a solution as detailed there 
[http://www.inonit.com/cygwin/jni/invocationApi/archive.html] :
1) create a jvm.def file :

EXPORTS
JNI_CreateJavaVM@12
JNI_GetDefaultJavaVMInitArgs@4
JNI_GetCreatedJavaVMs@12

2) generate the import library :

dlltool --input-def jvm.def --kill-at --dllname jvm.dll --output-lib libjvm.dll.a


This solution seems to be very common for dealing with the cooperation 
between MinGW and Native Java 
[http://java.freehep.org/jcvslet/JCVSlet/show/freehep/freehep/lib/WIN32-g++/README.txt/1.3]. 


But it does not answer why I need this trick for the jvm lib and not for 
the jawt one...

So in the Makefile.in I put :

ifeq ($(OS_ARCH),WINNT)
EXTRA_DSO_LDOPTS+= \
        $(JAVA_HOME)/lib/jawt.$(LIB_SUFFIX) \
        -L..\..\..\..\..\JRex_patches\jvm -ljvm \
        $(NULL)

(JRex_patches\jvm is the directory where the linker can find the new 
generated import library).

With all these patches applied (see previous postings) I can build JRex 
without DOM but when I try to test the example I get :
