I think you can merge the patch to FreeBSD 4.3 or others, because the
patch consists of the following three parts and we don't change the
source code of base system except gcc.

1. gcc extension, which is periodically submitted to gcc-patch mailing
list by Hiroaki Etoh.

2. patch to the Makefile in src/libexec/rtld-elf, which doesn't change
the source code itself. It links the object file "stack_smash_handler"
compiled with position independent option.

3. patch to the Makefile in src/sys/booti386/loader, which adds the
library "-lgcc -lc" for linking loader.

I'll appreciate receiving the result whether the patche is applied to
FreeBSD 4.3 or FreeBSD 5.0.

Regards,
Hiroaki Etoh
