You usually only need that on 32bit hosts. On 64-bit hosts, the default
interface already uses long. which should be 64bit (unless for braindamaged
win32, but things are there different anyway). Also, even for 32-bit hosts,
you usually can enforce the interface to use 64bit file pointers by using
_LARGEFILE_SOURCE and _FILEOFFSET_BITS=64 without having to change your code.
Beside that, it is really only important for things like you mentioned
(accessing the recorded avi file). For the gemdos emulation, it is irrelevant,
since neither mint nor TOS can handle 64bit file offsets.
