While attempting to compiling a kernel using an unmodified /usr/src/sys/i386/conf/GENERIC kernel conf file I encounter this show stopper.

I did not altered the source in any way after having installed it via  /stand/sysinstall.  I attempted to build another kernel after running make clean with the same effect. I then deleted my source tree and re-built it via CVSup and once again attempted to compile a kernel after running a make clean. I recived the same error. I once again deleted my source tree and reinstalled it using /stand/sysinstall. Then, I once again repeated the build process (make clean followed by make buildkernel KERNCONF=GENERIC ....) and every time recieved the same error. Then i edited the GENERIC kernel configuration file commenting out device wlan upon attempting a make buildkernel KERNCONF=GENERIC  error disappeared  and compilation was successful.
>How-To-Repeat:
try to recompile a stock kernel.
      
>Fix:
I label this as a temporary fix but not even a true worka around  because it disables wireless device support completely.
edit the GENERIC kernel configuration file commenting out device wlan.
