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.
