Just to note: I was not trying to use a 3.86 build of cat.c with a version 
Syslinux 4. 

With 3.x I would copy the modified cat.c to the com32/cmenu directory, and 
run the make in the com32 directory, and it would build the cat.c32 and that 
could then be copied with the original isolinux.bin from the download.

With version 4, this cat.c32 would just freeze. Did a build of the complete 
syslinx 4, and copied the isolinux.bin and .c32 programs I use, and this has 
the cat.c32 working as before. The display.c32 thou does not work, and it is 
unchanged. 

The display.c source seems to be exactly the same as earlier version, so not 
sure why it doesn't seem to work. Even running it with no file name does 
display the error message that no file was included.
