>Description:
 If we specify 'device ndis' and 'options NDISAPI' in kernel configuration
file, then we will not be able to build such kernel due to a syntaxical errors
in file /sys/compat/ndis/subr_ntoskrnl.c
>How-To-Repeat:
 Cvsup 6.0-CURRENT, put
options NDISAPI
device ndis
device wlan
 into kernel config and build a kernel. The compiler will spit a bunch of errors
for subr_ntoskrnl.c
>Fix:
 Just specify explicit typecast of dpc->k_lock in KeRemoveQueueDpc()
