On many DOS compilers, the allocated memory pool is taken from a single
segment, i.e. 64K max.  This is true EVEN IN LARGE MODEL.  It is simply
an outright laziness on the part of the library writers not to take
this into consideration.  There may be performance problems using 4-byte
pointers, but that could be remedied by having optional libraries for those
cases; the linker would search the specialized libraries first and link
in the correct routines and ignore the default ones.  Another solution is
to use 2-byte pointers everywhere in a segment except for the first and last
ones.

Yet it is not done.  Chalk one up to the general immaturity of MSDOS software.
