Just in case anyone has similar problems in the future, I've made an
explicit list of the steps I took in getting a linux->dos cross-compiler
working with gcc 3.0.1 and binutils 2.11.2.

Thanks again to everyone!

The procedure is below,
Will Robinson

Plaintext description of the procedure for installing
a linux->DOS cross-compiler using gcc-3.0.1 and
binutils-2.11.2:

(insert your username in place of wsr23)

1. (as root) mkdir -p /opt/djgpp

2. chown -R wsr23.wsr23 /opt/djgpp

3. mkdir /opt/djgpp/i586-pc-msdosdjgpp

4. download djcrx203.zip from www.delorie.com

5. unzip -a djcrx203.zip (in /opt/djgpp/i586-pc-msdosdjgpp)

6. mkdir ~/temp

7. download binutils-2.11.2.tar.gz, gcc-3.0.1.tar.gz

8. untar binutils-2.11.2.tar.gz and gcc-3.0.1.tar.gz in ~/temp
   (tar xvzf)

9. cd binutils-2.11.2

10. mkdir djbuild

11. cd djbuild

12. ../configure --target=i586-pc-msdosdjgpp --prefix=/opt/djgpp

13. make

14. make install

15. download gcc30s2.zip from DJGPP archive (google search); unzip to a
temp directory

16. apply all .diff's included in gcc30s2.zip to the corresponding files
in the
    ~/temp/gcc-3.0.1 tree.  [Don't apply Makefile.am.diff]

17. copy all non-.diff files included in the diffs directory of
gcc30s2.zip to the
    corresponding directories in ~/temp/gcc-3.0.1

18. add
    #include_next "limits.h"
    before the final #endif in ~/temp/gcc-3.0.1/gcc/glimits.h

19. mkdir -p
~/temp/gcc-3.0.1/djbuild/i586-pc-msdosdjgpp/libstdc++-v3/include/i586-pc-msdosdjgpp/bits

20. copy ~/temp/gcc-3.0.1/libstdc++-v3/config/os/djgpp/bits/*
to
~/temp/gcc-3.0.1/djbuild/i586-pc-msdosdjgpp/libstdc++-v3/include/i586-pc-msdosdjgpp/bits/

21. chmod ugo-w
~/temp/gcc-3.0.1/djbuild/i586-pc-msdosdjgpp/libstdc++-v3/include/i586-pc-msdosdjgpp/bits/*

22. cd ~/temp/gcc-3.0.1

23. mkdir djbuild

24. cd djbuild

25. ../configure --target=i586-pc-msdosdjgpp --prefix=/opt/djgpp
--enable-languages="c,c++"

26. make

27. make install

28. cd /opt/djgpp/i586-pc-msdosdjgpp/src/stub

29. gcc -o stubify stubify.c

30. cp stubify /opt/djgpp/bin

31. cp stubify /opt/djgpp/i586-pc-msdosdjgpp/bin

32. su -c "ln -s /opt/djgpp/bin/i586-pc-msdosdjgpp-gcc /usr/bin/gcc-dos",
    etc. for all /opt/djgpp/bin/i586-pc-msdosdjgpp-* files.

33. su -c "ln -s /opt/djgpp/i586-pc-msdosdjgpp
/usr/local/i586-pc-msdosdjgpp"

34. ln -s /opt/djgpp/lib/gcc-lib/i586-pc-msdosdjgpp/3.0.1/*
/opt/djgpp/i586-pc-msdosdjgpp/lib/

35. ln -s /opt/djgpp/i586-pc-msdosdjgpp/lib/libstdc++.a
/opt/djgpp/i586-pc-msdosdjgpp/lib/libstdcxx.a
