The aim of this ongoing project is to keep functional and available on modern UNIX-type systems various older toolchain components (compilers, assemblers, linkers, etc). for use not only in portable application development and portability testing, but also for the compiling of historic and legacy code.

NOTE: This project is still at an experimental stage, and various changes and additions are planned. While the available components are usable, some are in an unpolished state and others are in the process of revision.

Classic C Compilation System (C3S)
An a.out-based x86 (IA-32) C compilation system supporting K&R C, "traditional C", and ANSI C up to and including the 1989 standard.
