Jim has said he would like a 32-bit DOS and/or multitasking and/or
other improvements (e.g. more *nix tools a la GNUish). But FreeDOS
developers are few and far between. Volunteers sorely needed, even for
non-programming stuff.

Anyways, FreeDOS-32 does supposedly compile with DJGPP (although I
haven't tried), but it stalled a few years ago with no activity in
sight (sadly). Even the latest beta was never officially released (see
the mailing list for links). I guess the authors just got too busy or
lost interest. (BTW, FD32 apparently uses real FreeDOS to "boot" into
the 32-bit version.)

FreeDOS does support FAT32 but no LFN stuff at the kernel level (like
closed src ROM-DOS and buggy RxDOS do). Actually MS' VFAT LFN hack is
patented anyways (doh). But yes, you can use third-party TSR tools
like DOSLFN or StarLFN. And nobody has bothered even starting to port
any other file systems (e.g. ext2/3/4).

And just for the record, FreeDOS FAT32 has a 2 GB file size limit due
to a). few people needing it, and b). compatibility issues (i.e. how
does Windows do it? how to not break compatibility with other apps
written for such?), and c). no kernel hackers but Eric Auer currently
available to consider it (and he never needs > 2 GB files in DOS).
