One simpler possibility suggested by another poster is supporting
multiple extent files i.e. allocate up to 2GB chunks as required in
the DOS FS, and when you need more, reopen another (related) file on
the same FILE */handle. This would be doable by wrapping the existing
file calls in another layer, and maybe using the DJGPP FSEXT
facilities to be able to do (part of) it under the covers.
