From: Greg Ungerer <gerg@xxxxxxxxxxx>
When compiling for original 68000 or ColdFire targets you will get the
following warning when compiling arch/m68k/lib/memcpy.c:
CC arch/m68k/lib/memcpy.o
arch/m68k/lib/memcpy.c: In function ‘__builtin_memcpy’:
arch/m68k/lib/memcpy.c:13:15: warning: unused variable ‘temp1’
This is easily fixed by moving the definition of temp1 into the code block
where it is used.
