[OT] The FAR/NEAR keywords were actually introduced by Microsoft,

8086/Intel/DOS world.
Not so. As usual, Microsoft does not innovate. Those keywords
appeared with the assembly language for the 8088/8086, back around
1976. The amazing thing is that Microsoft actually used a
pre-existing standard. This may be tied in with the fact that they
bought their C compiler from somebody else (I forget who).
Sigh...
<off-topic trip down memory lane>
Microsoft's C compiler version prior to Version 3 were Lattice C
repackaged. Microsoft C 3.0 and later were their own in-house
compilers.
Neither Lattice nor Microsoft's pre version 3 compilers supported the
"near" or "far" extension keywords. Nor did they support the "tiny"
or "huge" memory models.
In fact, they did not support mixing pointer types or memory models.
Lattice came with four libraries, for the four possible combinations
of 16/32 bit code/data addressing. It was up to the user to link the
one matched the options passed to the compiler.
