FreeDOS 2038 is VERSION number sensitive in int 21.5a create temp file:

(text snippet from RBIL int 21.5a create temporary file)

>> AH = 5Ah CX = file attribute (see #01420 at AX=4301h)
>> DS:DX -> ASCIZ path ending with a '\' + 13 zero bytes to
>> receive the generated filename

>> Return: CF clear if successful
>> AX = file handle opened for read/write in compatibility mode
>> DS:DX pathname extended with generated name for temporary file

>> MS-DOS 5.0 and DR DOS 3.41/5.0 will insert a missing trailing
>> backslash before appending the generated filename, but due to

If you set VERSION to something different than 5.xx in config sys
then FreeDOS will behave in the more common DOS 3/4/6/7 style :-)

Please explain.
