GCC 2.7.2.2 and MC68K

[Eric DeVolder]

I've successfully installed Binutils 2.8.1 for --target=m68k-coff
--with-gnu-as --with-gnu-ld --nfp.  Now trying to install GCC 2.7.2.2
with the same configuration, I get quite a ways until the following occurs:

rm -f tmplibgcc2.a

_ashldi3 _ashrdi3 _ffsdi2 _udiv_w_sdiv _udivmoddi4 _cmpdi2 _ucmpdi2

  echo ${name}; \
  ./xgcc -B./ -O2  -DCROSS_COMPILE -DIN_GCC -DSVR4  -g -I./include
-I/usr/include  -g1  -m68000 -I. -I. -I./config -c -DL${name} \
      ./libgcc2.c -o ${name}.o; \
  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  /usr2/styx/gnu/m68k-coff/bin/ar rc tmplibgcc2.a ${name}.o; \
  rm -f ${name}.o; \
done

The error clearly indicates that while trying to build the libgcc2 for
-m68000, the ./xgcc is emitting an opcode which is not valid for
-m68000.  This form of the instruction is valid for 68020 and beyond,
but not 68000.

Any help?  Any patches for 2.7.2.2 to fix this problem?  The patch at the
Cygnus site doesn't correct this problem.
