Can't install aureal vortex driver.

When I try to install the aureal vortex driver with "make install20" I get the 
following output:

make install AUCHIP=AU8820
make[1]: Entering directory `/root/aureal'
cc -D__KERNEL__  -DMODULE -DAU8820 -mpentiumpro  -O6 -fomit-frame-pointer 
-Wall -pipe -I/usr/src/linux/include   -c -o au_audio.o au_audio.c
`-mpentiumpro' is deprecated. Use `-march=pentiumpro' or `-mcpu=pentiumpro' 
instead.
In file included from au_vortex.h:66,
                 from au_audio.c:49:

make[1]: *** [au_audio.o] Error 1
make[1]: Leaving directory `/root/aureal'
make: *** [install20] Error 2

Does anyone know what to do?
