I built my cross compiler (with help from net) by doing :

1) read INSTALL in gcc 

2) build binutils , gas using the right target 
 --target=i386-ibm-go32 --host=hp9k700 --with-minimal-bfd=yes

3) put the binaries in the right place (see 1)

4) Ftp djgpp's include files and libs (from version 1.10 a.out style)
   and put them in the right place (see 1)

4) build gcc with
 --target=i386-ibm-go32  --host=hp9k700 --with-gnu-ld --with-gnu-as
   Here I needed help. configure file needs to be changed as :


~/gcc-2.5.8>diff configure configure.org
538,543d537
<       i[34]86-ibm-go32)               # Intel 80386's running GO32/djgpp
<               cpu_type=i386
<               xm_file=i386/xm-dos.h
<               xmake_file=i386/x-sysv3
<               tm_file=i386/go32.h
<               ;;

This will create a gcc that will create an a.out file which can be
ftp'ed to a PC and run with go32. However only a.out style seems to be
working as binutils and gas are not aware of dj's switch to coff.

Hope this helps
