Whitesmiths C compiler: One of the earliest commercial C compilers available

Summary

Whitesmiths, Ltd. C Compiler Background The original Whitesmiths compiler was released in 1978 and compiled a version of C similar to that accepted by Version 6 Unix. It was an entirely new implementation, borrowing no code from Unix. When Whitesmiths released version 3.0 of its C compiler in 1985 it supported the emerging ANSI C standard. The Whitesmiths compiler had code generators for DEC PDP-11, Intel 8080/Zilog Z80, Intel 8086, Motorola MC68000, DEC VAX-11, IBM System/370 and IBM System/36. It was commonly used as a cross compiler. The company's president from 1978 to 1988 was P. J. Plauger. Whitesmiths - Wikipedia Making the C compilers available for download As the Whitesmiths C compilers are a very important contribution to the development of the use of the C language, I think that it is important that this software is not lost for the future. I recieved an e-mail reply from P.J. Plauger on 3 Apr 2021 where he is positive to making the compiler available for download. <pjp> I own all rights to the Whitesmiths C compiler. if you want to go to the trouble to package it so that it can be downloaded from such a site, II'll be happy to supply you with a letter giving limited rights to use it at no cost, at least for non-commerecial purposes, provided you supply me with a copy of the package you make. Glad you're still active after all these decades. I am too, but definitely slowed down by age. Best regards, P.J. Plauger </pjp> I have tried to get in contact with him to confirm that it is ok to put the C compiler in a public repository, but unfortunately I have not got any answer yet.
