>Description:
	
A sparc kernel with RASTERCONSOLE and either RASTERCONS_SMALLFONT or
RASTERCONS_FULLSCREEN will fail to build because of a routine that
is declared but not used (a2int()).

>How-To-Repeat:
	
config a kernel with either of the above options and watch the
make fail thus:

cc  -O2 -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -mno-fpu -I. -I../../../../arch -I../../../.. -DSUN4C -DSWAPPAGER -DVNODEPAGER -DDEVPAGER -DKTRACE -DSYSVMSG -DSYSVSEM -DSYSVSHM -DDIAGNOSTIC -DCOMPAT_43 -DCOMPAT_10 -DCOMPAT_11 -DFFS -DNFSSERVER -DNFSCLIENT -DCD9660 -DFIFO -DINET -DRASTERCONSOLE -DRASTERCONS_FULLSCREEN -DRASTERCONS_SMALLFONT -DBLINK -D_KERNEL  -c ../../../../arch/sparc/dev/fb.c
cc1: warnings being treated as errors
../../../../arch/sparc/dev/fb.c:364: warning: `a2int' defined but not used
*** Error code 1

Stop.
