The Small C compiler translates a subset of the C language into
assembly language. It runs under PC/MS-DOS 2.1 and later. Small
C is compatible with the Microsoft and Small Mac assemblers.
Small C takes full advantage of the ability of these assemblers
to generate relocatable object code, to maintain libraries of
relocatable modules, and to link separately compiled program
modules. It supports a small memory model with one code and one
data/stack segment.
CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS.
the newest version, support windows.
OXCC is a multipass, interpreting C compiler with several language extensions. It generates an Architecture Neutral Format (ANF) output and comes with a couple of example back ends. Programmers are expected to write additional back ends for their specific needs.
Simple C Compiler, Release 0.1.6
Simple C is a portable C compiler based on Small C/386. It is designed
to run on Linux, but it should be usable on any Unix-like operating
system for the x86 with minimal effort.
