problem linking with glu and win32ada

Hi,

I'm using the following:
GNAT GPL 2007-2
Windows 2000
win32ada

When with'ing win32.glu, I get a Linker error:
i:\progra~1\gnat\2007\lib\win32ada/libwin32ada.a(win32-glu.o):win32-glu.adb:(.text+0x7b):
undefined reference to `gluErrorString@[EMAIL PROTECTED]
'

objdump tells me that there is indeed a call to gluErrorString in
libwin32ada. Just how do i get it to resolve the name? -glu32 is given
in the linker options for both my project and win32ada.

Ciao,
     Christian
