dlls/d3d8/device.c: statement with no effect

[Gerald Pfeifer]

In dlls/d3d8/device.c I am getting the following warning (on FreeBSD):

/usr/bin/gcc -c -I. -I. -I../../include -I../../include -I/usr/X11R6/include -g -O2 -Wall -Wpointer-arith -mpreferred-stack-boundary=2 -gstabs+  -fPIC -D__WINESRC__  -D_REENTRANT -o device.o device.c
  device.c: In function `DrawPrimitiveI':
  device.c:475: warning: statement with no effect

Could someone please have a look? (If fixed about half a dozen portability
problems last week, but this one I'm having a hard time with.)
