[syslinux] COM32

[Mortaza Doulaty]

Maybe some bug: I've a file named 'somthing.config' which resides in
Windows/System32/ in a FAT32 partition, surprisingly I can not access to it,
failing with errno=2, but I can access any other files in that location. Is
the problem caused by its name and extension which is not in 8.3 format?
