Unix Tools For Windows
CodeBlocks With A full development environment. Took a while but CodeBlocks is now upto speed and in sync with the current release version. New version of CodeBlocks supports XML based configuration, so users can do specialized compiler support if needed. Changed away from the old Msys in favor of Msys2 which has better support for a lot of things like miktex. Old package is still there if you still need it but wont be developed on anymore. Loads of modifications compared to the Msys2 package from Alex, you can still update Msys2 packages from his server though. MinGW64 packages have to many changes compared to Alex version so those will not upgrade but im working on creating my own package server. Current Msys2/MinGW64 gcc is now 6.2.0-4 and binutils 2.27. New packages will be uploaded shortly. Stay tuned for more changes.
SDCC is a retargettable, optimizing standard C (ANSI C89, ISO C99, ISO C11) compiler that targets a growing list of processors including the Intel 8051, Maxim 80DS390, Zilog Z80, Z180, Rabbit 2000, gbz80, Motorola 68HC08, S08 and STMicroelectronics STM8 targets. There also is incomplete support for the Microchip PIC16 and PIC18.

A free COBOL compiler
GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. cobc translates COBOL source to executable using intermediate C, designated C compiler and linker. OpenCOBOL 1.1 became GNU Cobol 1.1 in 2013. GnuCOBOL 2.2 is the latest, version 3.0 is on its way. A programmer's guide, by Gary Cutler and Vincent Coen, is indexed at https://open-cobol.sourceforge.io together with more documentation. OpenCOBOL was written by Keisuke Nishida and Roger While, from 2001 to 2012. GnuCOBOL is also authored by Simon Sobisch, Ron Norman, Edward Hart, Sergey Kashyrin, Dave Pitts and Brian Tiffin.

Common Lisp compiler and runtime
A high performance Common Lisp compiler. In addition to standard ANSI Common Lisp, it provides an interactive environment including an a debugger, a statistical profiler, a code coverage tool, and many other extensions.
Lazarus is a free and open source development tool for the Free Pascal Compiler. The purpose of this project is to serve as a Code Repository, Wiki Knowledgebase and support site for converting existing components and libraries to work with Lazarus and the Free Pascal Compiler.
JSmooth creates standard Windows executable files (.exe) that smartly launch java applications. It makes java deployment much smoother and user-friendly, as it is able to find and run Java VMs by itself, or help the user get one if none are available.
Dual-target(32 & 64-bit) MinGW-W64 compilers for 32 and 64-bit windows
Projects joined MinGW-W64, and the new builds will be available on the MinGW-W64(https://sourceforge.net/projects/mingw-w64) site.

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.
A decompiler for Lua 5.1
unluac is a decompiler for Lua 5.1. It runs on Lua chunks that have been compiled with the standard Lua compiler. It requires that debugging information has not been stripped from the chunk. (By default, the Lua compiler includes this debugging information.) This program is written in Java. A JAR package is available in the downloads section so you don't have to compile it. It runs from the command line and accepts a single argument: the file name of a Lua chunk. The decompiled code is printed to the standard output. Here is an example usage of unluac: java -jar unluac.jar myfile.lua > myfile_decompiled.lua The current version also has pretty good support for Lua 5.0 and experimental support for Lua 5.2 and Lua 5.3.
