[DRBD-user] DRBD .7.2 compile issue - [drbd_bitmap.o] Error 1

[Dan Didier]

Thanks to Lars for pointing out some obvious issues with kernel
compilations I am now trying to compile DRBD .7.2 on my redhat 9 system
running kernel 2.4.20.31.9smp

When I try to make, I get the following:

[root at rome1 drbd]# make KDIR=/lib/modules/2.4.20-31.9smp/build/

    Calling toplevel makefile of kernel source tree, which I believe is
in
    KDIR=/lib/modules/2.4.20-31.9smp/build/

It seems that there is a conflict, but I am at a loss as to how to fix
this.  Does anyone know what the solution could be?
