68340 Board support

[Bob Stafford <bobstaff at snowhill dot com>]

I'm trying to build a cross compiler to generate code for a simple 68340

evaluation system. Whne linking a hello world program I get the
following errors

[bobstaff@snooker 340]$ m68k-coff-gcc hello.c -L
/usr/lib/gcc-lib/m68k-coff/2.95.2 -lgcc
/usr/m68k-coff/lib/crt0.o:../../../../src/libgloss/m68k/crt0.S:16:

/home/bobstaff/340/b-m68k-coff/gcc/../../src/gcc/libgcc2.c(.text+0x12):

/home/bobstaff/340/b-m68k-coff/gcc/../../src/gcc/libgcc2.c(.text+0x1a):
undefined reference to `_exit'
collect2: ld returned 1 exit status

I believe I probably need to provide some board support functions to get

rid of these errors. Can anybody point me in the direction of some docs
on the web that explain what functions I need to write and what they
should do. Alternatively are these functions available somewhere.

I'm using gcc-2.95.2,binutils-2.9.1 and newlib-1.8.2, running on a
Red HAT 6.1 linux host.

Thanks

Bob Stafford
