/* Common MINIX configuration.
 * This file maps GCC defines to MINIX defines
 *
 * For this to work properly, the order in the tm_file variable has
 * to be the following:
 *   minix-spec.h $arch/minix.h minix.h
 *
 * minix-spec.h	: specifies default arch-independent values
 * $arch/minix.h: redefines as needed default minix values
 * minix.h	: maps GCC defines to the minix defines.
