The earlierst reference I could find is in a German book on Borland's
Turbo C programming environment (Ekkehard Kaier, Edwin Rudolfs,
»Turbo C Grundkurs«, first published in 1988). It is not generally
available on current Microsoft platforms, and there are online
references that claim that it was not part of earlier Microsoft C
environments. This suggests that the previous speculative attribution
to MS-DOS (sic) was incorrect.
