Hi all,
I downloaded the Grub's code from
here<http://grub.sourcearchive.com/documentation/0.97-1ubuntu9/files.html>.
Then just for testing I put following lines of code in grub/main.c. What I
wanted is to have "#Here I come..." string appended at the end of
/boot/grub/menu.lst. But I got stuck while compiling the source code. I
don't know what have I missed...

Then after saving main.c I configured the package and when i ran 'make', I
got:

Grub Legacy is dead for us. GRUB2's source code is much easier to
understand and contributions to it are actually useful.

You shouldn't use any stdio in grub (it works in grub-util but won't in
grub on boot). Actually writing facilities in any grub are rudimentary
by design to avoid any danger of filesystem corruption
