[SDL] fbcon compile error

[Chain]

Hello all, I am a new user for SDL, just download the code from SVN and
compiling SDL for ARM, I use follows command to configure, it is OK.

./configure --prefix=/home/clin/DATA/arm-ffmpeg --enable-video-fbcon
--disable-video-qtopia --disable-video-photon --disable-video-direct
--disable-video-ggi --disable-video-svga --disable-video-aalib
--disable-video-dummy --disable-video-dga --disable-arts --disable-esd
--disable-alsa --disable-video-x11 --disable-nasm --disable-debug
--disable-joystick-amigaos --disable-joystick-beos
--disable-joystick-bsd --disable-joystick-darwin --disable-joystick-dc
--disable-joystick-linux --disable-joystick-macos
--disable-joystick-mint --disable-joystick-win32 --disable-joystick
--host=arm-linux --disable-3dnow

and then go to make.

but there are many error message about the fbcon. Like, 

In file included from ./src/video/fbcon/SDL_fb3dfx.h:26,
                 from ./src/video/fbcon/SDL_fb3dfx.c:26:

And I enter the code, find that there is no these parameters indeed. 
Why has this problem?
