Hi Jeff,

The right mailinglist for discussing GRUB 2 is grub-devel.  Please

It is related to nested functions.  For example there is this nested
function:

static int grub_ls_print_files (const char *filename, int dir)
{
 ...
}

I think this should be:

auto int grub_ls_print_files (const char *filename, int dir);

int grub_ls_print_files (const char *filename, int dir)
{

}

I have tested this and it seems to be fixed when using my patch:

http://lists.gnu.org/archive/html/grub-devel/2005-04/msg00048.html

When this patch is committed and the build errors are fixed, I will
contact you about it.

Thanks,
