Looking at \src\H\VERSIONC.H, this seems to be DOS 4.0

...which was buggy and quickly followed by 4.01

Are they releasing the source to 4.01 too? Would be neat to see a diff of those.

It’s hard to tell. According to Wikipedia, DOS 4.0 is different than 4.00

> MS-DOS 4.0 (multitasking) and MS-DOS 4.1 – A separate branch of development with additional multitasking features, released between 3.2 and 3.3, and later abandoned. It is unrelated to any later versions, including versions 4.00 and 4.01 listed below
