There is a couple of functions which defines 'ah' variable but
never use it in real so that gcc 4.6.x series does complain on
me as
CC bios/bios-rom.bin
bios/int10.c: In function ‘int10_putchar’:
bios/int10.c:86:9: error: variable ‘ah’ set but not used [-Werror=unused-but-set-variable]
bios/int10.c: In function ‘int10_vesa’:
bios/int10.c:96:9: error: variable ‘ah’ set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
so get rid of them.
