System: NetBSD klei.intern.polderland.nl 1.4.2 NetBSD 1.4.2 (KIELDRECHT) #11: Wed Jul 19 14:00:31 CEST 2000 root@kieldrecht:/usr/src/sys/arch/i386/compile/KIELDRECHT i386


>Description:
	cd pkgsrc/lang/gcc &&
	make install &&
	ls /usr/pkg/gcc-2.95.2/lib/libstdc++*

	and notice libstdc++.so.2.10 is missing.
>How-To-Repeat:
	see above.
>Fix:
	I used something like the patch below. This also includes my
	patch for pr pkg/12153. I don't know if other architectures than
	i386/a.out suffer from this but this is easily changed.

	There is a target in the Makefile in
	${WRKDIR}/objdir/${MACHINE_GCC_PLATFORM}/libstdc++ for making
	libstdc++.so.2.10.0 (note extra .0) but that seems to call gcc
	in an incorrect manner that produces lots of warnings like

	ld: /usr/tmp/lang/gcc/work/objdir/gcc/libgcc.a(new.o): RRS text
	relocation at 0x2b2fa for "___get_eh_context"

	so I chose not to use it. Adding the option -nostdlib avoided
	this, but the result still had a slightly different size.
