This is needed only, if you don't have a /bin/sh.exe on the
drive, where you build gcc. So created that and you don't need
to modify the Makefile.

This is, because not all my patches which I did for the DJGPP
port of gcc 2.8.0 are already included in gcc 2.8.1. So apply the
following patch to the main configure script:

*** configure.in~	Wed Mar 18 22:13:04 1998
--- configure.in	Wed Mar 18 22:13:12 1998
***************
*** 862,867 ****
--- 862,868 ----
  		xm_file=i386/xm-go32.h
  		tm_file=i386/go32.h
  		tmake_file=i386/t-go32
+ 		xmake_file=i386/x-go32
  		gnu_ld=yes
  		gas=yes
  		;;


and then create the new file config/i386/x-go32

---CUT HERE---
# translate the version string, so it can be used on DJGPP, where only
# one dot in filename is allowed

# to avoid recursion when redefining $(version)
_version:=$(version)
__version=$(word 1,$(subst ., ,$(_version))).
version=$(__version)$(subst .,,$(subst $(__version),,$(_version)))

SYSTEM_HEADER_DIR=$(DJDIR)/include
X_CPPFLAGS=-DSTANDARD_INCLUDE_DIR=\"\$$DJDIR/include\" \
	   -DSTANDARD_INCLUDE_COMPONENT=\"\"
FIXINCLUDES=fixinc.djgpp

# when building a native compiler for DJGPP, make the target_alias
# a shorter name, since otherwise it will produce some problems, when
# using the same gcc once with long filenames and once with short (8+3)
# filenames
ifeq ($(findstring -pc-msdosdjgpp,$(target_alias)),-pc-msdosdjgpp)
target_alias=djgpp
endif
--------CUT HERE---------

now run autoconf and djconfig.sh
