The update is significant to incorporate the reversed fixes for 4.01! Thanks to hharte!

I've been able to build this from both MS-DOS 5 & Win32.
SRCSTACK includes the boot stack fix, and is suitable for building under MS-DOS
dos401_win32 has the same sources, but win32 friendly makefiles that allows for building through MS-DOS player ( http://takeda-toshiya.my.coocan.jp/msdos/ ), along with some native tools I've found along the way.
And finally a 1.44MB floppy image. It doesn't have the right labels so select isn't happy (SELECT MENU). But it looks sane now!
