[syslinux] 5.01 pre3 CONFIG directive

Hi Matt,

Unfortunately, it fails with 5.01-pre3.

I have uploaded a small ISO image with 5.01pre3 which fails.

Initially, it failed when I used the CONFIG directive:
"Failed to load libutil_com.c32"
"Failed to load COM32 file ../boot/syslinux/menu.c32"

I then added the PATH directive (although I don't understand why it 
should be added in this case), so the first CONFIG seems to work (at 
least one time).

In each cfg file in the ISO I have added comments for guidance, where 
I try to clarify (and I also ask there, what is that is not being 
clear to me).

What I have not added in the comments in the image is how to make it 
fail (tested in VBox):
1_ Boot.
2_ Select LABEL "mainmenu".
3_ Select LABEL "pwd1". See the result.
4_ In the "boot:" prompt, press [ENTER].
5_ Select LABEL "pwd1" again.
Now it hangs.


I hope it helps to find out what's wrong (or to find out what is that 
I am not understanding as I should).

I also have the equivalent ISO image with ISOLINUX 4.06. It doesn't 
need the lib*.c32 files nor the PATH directive, and it does not hang.
