It was in 16bit MS C Compiler, Watcom C, Borland C, Zorland/Zortech
C/C++. In fact the availability of memory models exceeding small and
large was a desirability of 8086 compilers. Such large code small data,
small code, large data and huge (large code and large data). In fact the
legacy of NEAR and FAR keywords lived on for a long time.

Certainly MS Visual Studio 2019 includes header files for code designed
for Windows (windef.h) with the following legacy definitions still:

#ifndef pascal
#define pascal      __ONLY_IN_WINELIB(__stdcall)
#endif
#ifndef _pascal
#define _pascal     __ONLY_IN_WINELIB(__stdcall)
#endif
#ifndef __export
#define __export    __ONLY_IN_WINELIB(__stdcall)
#endif
#ifndef near
#define near        __ONLY_IN_WINELIB(/* nothing */)
#endif
#ifndef far
#define far         __ONLY_IN_WINELIB(/* nothing */)
#endif
#ifndef _near
#define _near       __ONLY_IN_WINELIB(/* nothing */)
#endif
#ifndef _far
#define _far        __ONLY_IN_WINELIB(/* nothing */)
#endif
#ifndef NEAR
#define NEAR        __ONLY_IN_WINELIB(/* nothing */)
#endif
#ifndef FAR
#define FAR         __ONLY_IN_WINELIB(/* nothing */)
#endif

Segment registers still exist on x86-64 CPUS.
