Just test yourself ... it is funny:

VERSION=5.10-pre2
tar xvJf syslinux-${VERSION}.tar.xz
mkdir -p build/boot/isolinux
for n in modules/ifcpu64.c32 elflink/ldlinux/ldlinux.c32 \
gpllib/libgpl.c32 samples/hello.c32 lib/libcom32.c32 ; do
     ls -lah syslinux-${VERSION}/com32/${n}
     cp -v syslinux-${VERSION}/com32/${n} build/boot/isolinux/
done
cp -v syslinux-${VERSION}/core/isolinux.bin build/boot/isolinux/
cat > build/boot/isolinux/isolinux.cfg << EOF

DEFAULT switch
PROMPT 1
LABEL switch
COM32 /boot/isolinux/ifcpu64.c32
APPEND hello -- hello
LABEL hello
COM32 /boot/isolinux/hello.c32

EOF

xorriso -as mkisofs -c boot/isolinux/boot.cat \
-b boot/isolinux/isolinux.bin -no-emul-boot \
-boot-info-table -boot-load-size 4 \
-V TEST -o test.iso -r build

Sorry, I pressed "send" too quick. There was one line break too much. It 
is really strange since at least it works up to this stage, both with 
the official binaries as well as with self compiled binaries.

The next step was too see how vesamenu.c32 behaves:

for n in modules/ifcpu64.c32 elflink/ldlinux/ldlinux.c32 \
gpllib/libgpl.c32 samples/hello.c32 lib/libcom32.c32 \
menu/vesamenu.c32 menu/menu.c32 cmenu/libmenu/libmenu.c32 \
libutil/libutil.c32 ; do
     ls -lah syslinux-${VERSION}/com32/${n}
     cp -v syslinux-${VERSION}/com32/${n} build/boot/isolinux/
done

cat > build/boot/isolinux/isolinux.cfg << EOF

DEFAULT switch
PROMPT 1
LABEL switch
COM32 /boot/isolinux/ifcpu64.c32
APPEND hello -- hello
LABEL hello
COM32 /boot/isolinux/vesamenu.c32
APPEND /boot/isolinux/isolinux.cfg

EOF

This also works, no matter if the line "PROMPT" exists or not. So you 
must be right with the guess that my config is somehow broken. I will 
rebuild the config (it is pretty nested) file by file and report again 
if it fails again.

Mattias
