(MOTOROLA_DELTA): Defined.

(HAVE_SYSVIPC, BAT68K, BAT_ALLOCA): Deleted--obsolete.
(STACK_DIRECTION, HAVE_X_WINDOWS): Deleted--configure knows.
(C_SWITCH_MACHINE): Set to -ga if using the Green Hills compiler.
(LIB_STANDARD, LIB_MATH): Defined to the 68881 versions.
(LIBS_SYSTEM): -lbsd brings sigblock and sigsetmask.
(sigsetmask): Undefined--it is in -lbsd.
(LDAV_SYMBOL): Undefined--we have no such thing.
(KERNEL_FILE): Defined to "/sysV68".
(BSTRING, HAVE_SELECT, HAVE_UNISTD_H, HAVE_TIMEVAL): Defined.
(SIGNALS_VIA_CHARACTERS): Defined.
(memmove): Defined as memcpy--we have no memmove.
(SIGIO, INTERRUPT_INPUT): Undefined--not yet tested.
(SHORT_FILE_NAMES, CLASH_DETECTION): Defined.
