glut and linking errors

Hello, I checked out cvs sources of Mesa yesterday or the day before that, 
and I was able to build them successfully, including glut, on Windows using 
the very latest Visual C++. I couldn't build them with MinGW, however.

Anyway, I need to use my freshly built Mesa binaries with Cygwin and my 
first problem was getting a simple test program to link. The test program 
involves calls to both gl, glu and glut-functions. I created .a-files of the 
three dll:s (opengl32, glu and glut) using these steps:

pexports opengl32.DLL > opengl32.def
dlltool --input-def opengl32.def --dllname opengl32.DLL --output-lib 
libopengl32.a -k

pexports GLU32.DLL > glu32.def
dlltool --input-def glu32.def --dllname GLU32.DLL --output-lib libglu32.a -k

pexports GLUT32.DLL > glut32.def
dlltool --input-def glut32.def --dllname GLUT32.DLL --output-lib 
libglut32.a -k

Then, I copied the resulting .a-files to Cygwin's /usr/lib/w32api directory.

But, when I try to build my simple test program, I get undefined references 
for all calls to glut-functions. The Makefile is:
CC = gcc
CFLAGS 
= -Wall -W -ansi -pedantic -g -O0 -I/home/mikael/mesacvs/Mesa/include -DWIN32 
 -c -o
LDFLAGS = -lopengl32 -lglu32 -lglut32 -o $(EXEC)
EXEC = 1-9.exe
OBJECTS = simple1_9.o

all: $(OBJECTS)
 $(CC) $^ $(LDFLAGS)

%.o: %.c
 $(CC) $(CFLAGS) $@ $<

clean:
 rm -f $(OBJECTS) $(EXEC) *~ *.stackdump

Here's the exact error when building my test program:
$ make
gcc -Wall -W -ansi -pedantic -g -O0 -I/home/mikael/mesacvs/Mesa/include -DWIN32 
 -c -o simple1_9.o simple1_9.c

simple1_9.o: In function `idle':

reference to `_glutMainLoop'
collect2: ld returned 1 exit status
make: *** [all] Error 1

So, I used nm to check the first undefined function it complains about, 
glutPostRedisplay:
$ nm /usr/lib/w32api/libglut32.a | grep _glutPostRedisplay
00000000 T __glutPostRedisplay <at> 0
00000000 I __imp___glutPostRedisplay <at> 0

So, it's there but it's decorated (hope that's the correct term). Then I 
check a function in libopengl32.a my program calls that I dont get an 
undefined reference for:
$ nm /usr/lib/w32api/libopengl32.a | grep _glPopMatrix
00000000 I __imp__glPopMatrix
00000000 T _glPopMatrix

It's there, of course, but unlike the glut-functions, no decorations. So I 
use sed to remove stuff from the glut-def-file (before creating the .a-file 
using dlltool):
# I'm sure these four lines can be turned into one.
cat glut32.def | sed 's/^_//' > glut32.def.temp
mv glut32.def.temp glut32.def
cat glut32.def | sed -e 's/@.*//' > glut32.def.temp
mv glut32.def.temp glut32.def

And now the program links successfully! But, it doesn't help me, because 
when I try to run the resulting executable I get an error message box 
saying:
The procedure entry point glutCreateWindow could not be located in the 
dynamic link library GLUT32.DLL
glutCreateWindow is the fifth call to a glut function my program makes. It 
seems to be able to call glutInit(), glutInitDisplayMode(), 
glutInitWindowPosition(), and glutInitWindowSize() correctly, but I'm not 
sure about that.

I don't understand these tools well enough to solve it, but surely here 
does? I would be very grateful for any assistance. I don't know how it 
works, but it seems the programs loads the DLL at runtime and since I've 
tampered with the decorations it cannot find any functions. But how can I 
get the program to link if I dont tamper with the decorations??

Please help if you can!
