Ok.  Till then, may I ask for your help to integrate ncurses into
minios?  I'm not familiar with the build system.  Basically, I think I
got the ncurses library built for the minios target, but can't use it
in my c stubdom yet, it get undefined references:

wferi@rs22:~/xen/xen-3.3.1/extras/mini-os$ ld -nostdlib 
-L/home/wferi/xen/xen-3.3.1/stubdom/cross-root-i686/i686-xen-elf/lib 
-L/home/wferi/xen/xen-3.3.1/stubdom/ncurses-x86_32/lib -m elf_i386 -T 
arch/x86/minios-x86_32.lds 
/home/wferi/xen/xen-3.3.1/stubdom/mini-os-x86_32-c/mini-os.o -o 
/home/wferi/xen/xen-3.3.1/stubdom/mini-os-x86_32-c/mini-os
/home/wferi/xen/xen-3.3.1/stubdom/mini-os-x86_32-c/mini-os.o: In function 
`grub_ncurses_getxy':
/home/wferi/xen/grub2/util/console.c:267: undefined reference to `stdscr'
[...]

(Yes, I'm trying to build a PV-Grub2 for getting LVM support :)

Of course if I add -lncurses to the above command, I get lots of
undefined references to the libc functions from ncurses.
Sure it's possible to find out, but it would be nice if you could
spare me a few cycles if you don't mind.  At least I wouldn't waste
further effort banging my head against the wrong wall.
