I haven't tested yet the same situation in any of the Linux-based 
installers. Under the described situation, syslinux.com 5.00pre10 
leaves both, ldlinux.c32 and ldlinux.sys, in "/"; syslinux.exe leaves 
only ldlinux.sys (deletes ldlinux.c32 only) and you are saying that 
the Linux-based installers are able to create the new directory.

I wouldn't had expected the SYSLINUX installers to create any 
directory, but if the Linux-based installers are already creating the 
destination directory, it makes sense that all the installers should 
be behaving the same way if at all possible.

Really? I can't reproduce the exact same behavior as in 4.06. Either 
nothing happens (goes back to the boot prompt without showing 
anything), or it shows additional "info" after "Hello World!". Maybe 
the additional info is useful for someone and it is shown on purpose?
