I have a gcc-2.3.2 running on my 386bsd-system. It is generating code for 
the mc68020/30/40.

You, i.e. the compiler, needs libgcc.a, with is a libgcc1.a combined with a
libgcc2.a. There is a line in the INSTALL manual how to build this.

To do so you need a cross-assembler and a cross-linker. Take the binutils  and gas 
   (9.Feb.1993)
    binutils-2.0.tar.Z   (try to get a version from this year)
    gas-1.93.tar.Z       (the 1.92.3 didn't know the '30 and up allright)

OK, now you run configure. I told configure, that I have a 'sun3' as target.
( there must be a better way).
  > configure --host=i386--bsd --target=sun3 --prefix=/usr/gt/local
  > gmake LANGUAGES=c LIBGCC1=libgcc1.a OLDCC=./xgcc

It may be that your 'as' and your 'ld' are not at the right place - put links
to the right place. If you are building the libgcc1.a and there is the error
about a wrong switch 'm' 'c' '6' '8' '0' .... the you are using your home-as.

Then the cc is complaining about some missing #includes, if you have time,
solve the error or do it like me, comment the lines out.

when the gmake dies type:
 >  gmake LANGUAGES=c LIBGCC1=libgcc1.a OLDCC=./xgcc  install

Now you have something to play with.


OH, wait at some place the gmake is dying with .... specs ....
type:
  >  ./xgcc -dumpspecs > specs

In this specs file there are information, which libs crt0.o ... gcc need.
edit this file, if there are things in you don't have ( mcrt0.o lib??? ).


May be the best idea is that someone with knowledge and english writing 
capabilities build a FAQ-how-to-build-a-cross-compiler-including-how-to-
build-a-g++-cross-compiler-starting-with-a-new-lib

Hope this helps a little.
