So why should we force these MS-DOSisms on the rest of the C-speaking
world? This is yet another kludge around the Intel iAPX?86
architecture (or lack thereof :-), just like "near" and "far". Tell
me, what does "near" mean on a 68000 system? I can call C routines
from the Unix fortran compiler WITHOUT declaring the C routine to be
of "fortran calling sequence." Let's not put these kludges in a C
language standard. If your programming environment needs them, let
them be (non-portable) extensions to the standard needed to support
your (non-) operating system!
