Note: libg++ depends upon some relativly recent changes to the system
includes.  If you haven't updated to current (and done a make build)
recently (since 1 Mar 98) then you need to first:

	cd /usr/src/include && make includes

Then you can continue with the steps Niklas specified.

This script worked for me.

#! /bin/sh
#
set -e

# Update system headers
#
(cd /usr/src/include &&
 make includes)

# Make gas
#
(cd /usr/src/gnu/usr.bin/gas &&
 rm -rf /usr/obj/gnu/usr.bin/gas &&
 make obj &&
 make &&
 make install)

# Make gcc
#
(cd /usr/src/gnu/usr.bin/gcc &&
 rm -rf /usr/obj/gnu/usr.bin/gcc &&
 make -f Makefile.bsd-wrapper obj &&
 make -f Makefile.bsd-wrapper includes &&
 make -f Makefile.bsd-wrapper &&
 make -f Makefile.bsd-wrapper install )

# Make gcc again, using the new gcc
#
(cd /usr/src/gnu/usr.bin/gcc &&
 rm -rf /usr/obj/gnu/usr.bin/gcc &&
 make -f Makefile.bsd-wrapper obj &&
 make -f Makefile.bsd-wrapper &&
 make -f Makefile.bsd-wrapper install )

# Make libg++ using the new gcc
#
(cd /usr/src/gnu/lib/libg++ &&
 rm -rf /usr/obj/gnu/lib/libg++ &&
 make -f Makefile.bsd-wrapper obj &&
