Copyright © 1996 Massachusetts Institute of TechnologySince tcc is heavily based on lcc, written by Chris Fraser and David Hanson, we also include the following copyright notice, which comes with lcc:

Permission to use, copy, modify, and distribute this software for any purpose, subject to the provisions described below, without fee is hereby granted, provided that this entire notice is included in all copies of any software that is or includes a copy or modification of this software and in all copies of the supporting documentation for such software.

lcc is not public-domain software, shareware, and it is not protected by a `copyleft' agreement, like the code from the Free Software Foundation.
lcc is available free for your personal research and instructional use under the `fair use' provisions of the copyright law. You may, however, redistribute the lcc in whole or in part provided you acknowledge its source and include this COPYRIGHT file.
You may not sell lcc or any product derived from it in which it is a significant part of the value of the product. Using the lcc front end to build a C syntax checker is an example of this kind of product.
You may use parts of lcc in products as long as you charge for only those components that are entirely your own and you acknowledge the use of lcc clearly in all product documentation and distribution media. You must state clearly that your product uses or is based on parts of lcc and that lcc is available free of charge. You must also request that bug reports on your product be reported to you. Using the lcc front end to build a C compiler for the Motorola 88000 chip and charging for and distributing only the 88000 code generator is an example of this kind of product.
Using parts of lcc in other products is more problematic. For example, using parts of lcc in a C++ compiler could save substantial time and effort and therefore contribute significantly to the profitability of the product. This kind of use, or any use where others stand to make a profit from what is primarily our work, is subject to negotiation.
