When I compiled the grub, I met some problems. I patched the patcheswhich I down from the http://os.inf.tu-dresden.de/~adam/grub/0.97/http://os.inf.tu-dresden.de/%7Eadam/grub/0.97/ . I patched the patches from the grub-0.97-os.1.diff to the grub-0.97-grub-0.97-os.5.diff, and I found they all have mistakes, the error from the grub-0.97-os.2.diff to the grub-0.97-os.5 were the same.Below are the errors:
pre_stage2_exec-bios.o : In function `get_cdinfo': /home/l4/Desktop/grub-0.97/stage2/bios.c:179: undefined reference to`__stack_chk_fail' pre_stage2_exec-bios.o: In function `get_diskinfo': /home/l4/Desktop/grub- 0.97/stage2/bios.c:317: undefined reference to `__stack_chk_fail' pre_stage2_exec-boot.o: In function `load_image': /home/l4/Desktop/grub-0.97/stage2/boot.c:759: undefined reference to `__stack_chk_fail' pre_stage2_exec-builtins.o: In function `blocklist_func': /home/l4/Desktop/grub-0.97/stage2/builtins.c:224: undefined reference to `__stack_chk_fail' pre_stage2_exec-builtins.o: In function `embed_func': /home/l4/Desktop/grub-0.97/stage2/builtins.c:1191: undefined reference to `__stack_chk_fail' pre_stage2_exec-builtins.o:/home/l4/Desktop/grub-0.97/stage2/builtins.c:1350: more undefined references to `__stack_chk_fail' follow
And the error when I patched the grub-0.97-os.1.diff is different. Theerror is below:

I compiled the grub under the ubuntu 7.04 environment, using the gcc-4.1.2and g++- 4.1.2.
And that's the problem. Grub up to including os.5 cannot be compiled with gcc4, you have to use gcc3 and then it works.
I have released an os.6 patch by now which also works with gcc4. For the stack protector thing I think you need to add -fno-stack-protector to CFLAGS. It could work then.
