First ... there's Richard Stallman. ... Secondly there's Leonard H. Tower, Gnu's teddy bear. Len is Gnu's first and so far only paid full time employee. Gnu's Hawk, Robert Chassell ... [and] Professor Hal Abelson and Professor Geral Sussman ... round out FSF's board of Directors ... Although I have a portable C and Pascal compiler, ... most of the compiler is written in Pastel, ... so it must all be rewritten into C. Len Tower, the sole full-time GNU staff person, is working on this, with one or two assistants.
Carol Botteron, Robert J. Chassell, Tami Friedman, Peter H. Salus, and Len Tower Jr. have left the FSF. Tami continues to volunteer for GNU as our Administrivia Coordinator. We thank them for their hard work.
Richard Stallman continues to do countless tasks, including refining the C compiler, GDB, GNU Emacs, etc. ... Finally, Len Tower continues to handle electronic administrivia (mailing lists, information requests, and system mothering).
Volunteers Phil Nelson and Len Tower work on our Web site. Len also remains our online JOAT (jack-of-all-trades), for mailing lists, gnUSENET newsgroups, information requests, etc.
Richard Stallman ... is currently continuing to develop the GNU C compiler. Hackers Len Tower, Richard Mlynarik, and Paul Rubin are doing various pieces of volunteer work as their time permits it, and Jay Fenlason continues to work full time on the GNU assembler and libraries.
Hoping to avoid the need to write the whole compiler myself, I obtained the source code for the Pastel compiler, which was a multiplatform compiler developed at Lawrence Livermore Lab. It supported, and was written in, an extended version of Pascal, designed to be a system-programming language. I added a C front end, and began porting it to the Motorola 68000 computer. But I had to give that up when I discovered that the compiler needed many megabytes of stack space, and the available 68000 Unix system would only allow 64k. ... I concluded I would have to write a new compiler from scratch. That new compiler is now known as GCC; none of the Pastel compiler is used in it, but I managed to adapt and use the C front end that I had written.
The basic algorithm is described in: "An O(ND) Difference Algorithm and its Variations", Eugene Myers, Algorithmica Vol. 1 No. 2, 1986, pp. 251-266; see especially section 4.2, which describes the variation used below."
The GNU C compiler is now available for ftp from the file /u2/emacs/gcc.tar on prep.ai.mit.edu. This includes machine descriptions for vax and sun, 60 pages of documentation on writing machine descriptions ... the ANSI standard (Nov 86) C preprocessor and 30 pages of reference manual for it. This compiler compiles itself correctly on the 68020 and did so recently on the vax. It recently compiled Emacs correctly on the 68020, and has also compiled tex-in-C and Kyoto Common Lisp.
I am a college student. Also the author of GNU grep, coauthor of GNU diff, and working on GNU sort
I wrote some of the original code in the GNU "diff" program. (It has since been replaced by other code.)
GNU DIFF was written by Mike Haertel, David Hayes, Richard Stallman and Len Tower.
I run the speaker bureau. Richard M. Stallman and Len Tower have done the bulk of our speaking engagements to date, but cannot be everywhere at once. Our cloning attempts, despite Richard's views on copying, have not yet succeeded. We would like more volunteers, with or without previous experience, to speak to people around the world and inform them about the software look-and-feel and patent issues.
The idea of using RTL and some of the optimization ideas came from the U. of Arizona Portable Optimizer, written by Jack Davidson and Christopher Fraser. ... Leonard Tower wrote parts of the parser, RTL generator, RTL definitions, and of the Vax machine description.
