Hi.
I'm following CLFS to make a custom Linux distro, and know I'm trying to
cross-compile GRUB to finalize my installation, but I'm having some
errors that I cannot fix, and I can't find suitable information to solve it.
I'm using GRUB-0.97, applied the 'grub-0.97-fixes-1.patch' patch, and
using the toolchain as described by CLFS (gcc-4.1.1).
This is my configure and make output:

The problem seems to be in a static declaration in netboot/main.c
(static struct bootp_t bootp_data) when the header 'etherboot.h' defines
this struct as non-static, and without a typedef keyword (struct bootp_t
{ ....... } ).
Can anyone help?
Thank you,
João Ramos
