Mhh... For me this is not true:

% ll /usr/bin/mkisofs                
lrwxrwxrwx 1 root root 11 May 31  2013 /usr/bin/mkisofs -> genisoimage
% genisoimage -eltorito-platform 0xEF
genisoimage: unrecognized option '-eltorito-platform'
[...]

Looks like my mkisofs is from cdrkit. What version do you have?

% pacman -Qo /usr/bin/mkisofs /usr/bin/genisoimage
/usr/bin/mkisofs is owned by cdrkit 1.1.11-3
/usr/bin/genisoimage is owned by cdrkit 1.1.11-3

main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Chris           get my mail address:    */=0;b=c[a++];)
putchar(b-1/(/*               gcc -o sig sig.c && ./sig    */b/42*2-3)*42);}
