        * config/i386/driver-i386.c: Include "coretypes.h" and "tm.h".
        (bit_SSSE3): New.
        (host_detect_local_cpu): Check -mtune= vs. -march=. Rewrite
        processor detection.

        * config/i386/i386.h (CC1_CPU_SPEC): Add -mtune=native for
        -march=native if there is no -mtune=*.

        * config/i386/x-i386 (driver-i386.o): Also depend on $(TM_H)
        coretypes.h.

Causes cross compilers targetting non-x86 architectures to fail to build:

/home/rearnsha/gnusrc/gcc-cross/trunk/gcc/config/i386/driver-i386.c: In
function
 `host_detect_local_cpu':
/home/rearnsha/gnusrc/gcc-cross/trunk/gcc/config/i386/driver-i386.c:64:
`PROCESS
OR_I386' undeclared (first use in this function)
/home/rearnsha/gnusrc/gcc-cross/trunk/gcc/config/i386/driver-i386.c:64: (Each
un
declared identifier is reported only once
/home/rearnsha/gnusrc/gcc-cross/trunk/gcc/config/i386/driver-i386.c:64: for
each
 function it appears in.)

Why is this file even needed for targetting an ARM system?

gcc configured with:

.../configure   --prefix=/work/rearnsha/gnu/
