The 16 bit compilers (like Digital Mars C++ for DOS) do have such
support. Just not the 32 bit ones (which the 6 byte pointers would be).
It could be added to DMC for 32 bits, but there is no point to it
because there's no demand for it.
DMC++ still supports 16 bit targets, but frankly, about 1 person a year
gets it for that purpose. 16 bits is dead, dead, dead.
