Subject: trying to compile jni lib under win2k

I'm trying to compile a small jni lib under win2k, but I'm getting a LOT of 
errors like this:

and it goes on for a few hundred more lines. I'm using a makefile I found in 
archives of this list:

 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

CC = gcc
CXX = c++

DEBUG = -g -Wall -O2
CXXFLAGS = $(DEBUG)
CFLAGS = $(DEBUG)
CPPFLAGS = -I /usr/include -I. -I$(JDK_ROOT)/include -I$(JDK_ROOT)/include/win32

JDK_ROOT = c:/java/1.3-sun

AS = as
DLLTOOL = dlltool
DLLWRAP = dllwrap

DLL_NAME = jcomm.dll
DLL_EXP_DEF = jcomm.def

all: $(DLL_NAME)

DLL_CFLAGS = -DBUILDING_DLL=1 -D_DLL=1
#DLL_LDFLAGS = -Wl,-e,__cygwin_noncygwin_dll_entry AT 12 -s
DLL_LDFLAGS = -Wl

# any extra libraries that your DLL may depend on.
DLL_LDLIBS = /usr/lib/libexpect526.a /usr/lib/libtcl80.a

DLL_SRCS  = jcomm.c
DLL_OBJS  = $(DLL_SRCS:.cc=.o)
DLL_OBJS := $(DLL_OBJS:.c=.o)

DLLWRAP_FLAGS = --output-def $(DLL_EXP_DEF) \

         $(IMAGE_BASE)

         $(DLLWRAP) $(DLLWRAP_FLAGS) -shared -o $(DLL_NAME) \
             $(DLL_OBJS) $(DLL_LDFLAGS) $(DLL_LDLIBS)

.c.o:
         $(CC) -c $(DLL_CFLAGS) $(CPPFLAGS) $(CFLAGS) -o $@ $<

# Note that we omit the $(DLL_CFLAGS) for client programs.
usedll.o: %o: %c
         $(CC) -c $(CPPFLAGS) $(CFLAGS) -o $@ $<

clean:
         -rm -f $(OBJS) $(DLL_OBJS) $(DLL_NAME) $(DLL_EXP_LIB) $(DLL_EXP_DEF) 
$(TESTPROGS)

 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

FWIW, It builds cleanly under RH Linux 7.2 and Mac OS X...
Any help would be greatly appreciated.

regards,

stewart
