XSCompiler : This MSDOS compiler generates 32-bit protected mode programs from a language that is C compatible, but includes classes and multiple inheritance. It comes with the standard C library, graphics, sound, multitasking, compression, animation, GIF, PCX, FLI/FLC, and other libraries. The compiler itself is compiled using this language.
GNAT : GNAT is an Ada95 compiler with the source code available in Ada95.
Rapid-Q : Rapid-Q is a free IDE and BASIC op-code compiler system for Win32, Linux, Unix... It is very easy to use and to integrate with many other goodies like mySQL, cgi, DirectX, Direct3D, GTK ...
Mingw : A very good Win32 port of the GNU GCC compiler (used in Dev-C++)
Cygwin : Another free and good Win32 port of GCC and GNU Utils
GCC : THE one and only GCC compiler system. Runs on nearly any system.
Phoenix/Envelop : Rapid Development under Basic.
B++ : B++ is a BASIC compiler built on top of C++ - it converts BASIC code to C++, and then calls C++ compiler to produce EXE (or DLL). Source code is in Free Pascal.
GNU Ada : Free ADA compiler.
Dev86 / BCC : x86 C/Assembler development tools (C compiler, assembler, linker). Under the GPL. Linux and DOS binary distributions available.
http://www.digitalmars.com : FREE C/C++ Compiler for DOS, Win & NT by theauthor of Zortech C++ .
Virtual Pascal : A tool of choice for 32-bit cross-platform development using the Pascal language. It is compatibile with Borland Pascal and Delphi, including the Run-Time Library (RTL), an optimizing compiler, a powerful integrated debugger, and comprehensive online documentation.
PlugSys Xbase compiler : PlugSys has a free edition and a Professional edition on their web site. It is a character based compiler for the Xbase(dbase, clipper) language. There are both DOSWin95/98/NT and Linux version. Same code compiles on either system. Also has a server page tool (free and pay versions). The documentation that comes with the download is great. Free version only requires registration to download.
Context programming language : Simple programming language and compiler for MS-DOS with sources and sample programs on it's own input language by Andrei V. Khokhlov
Babya : B++ compiler for DOS with setup and Windows 9x support.
OpenWatcom : Open Watcom is a joint effort between SciTech Software, Sybase®, and a select team of developers, which will bring the Sybase Watcom C/C++ and Fortran compiler products to the Open Source community.
Self : A port of a compiler for the Self programming language to Linux. The system was originally developed at Stanford University and Sun, and it forms the technological base of the Java Hotspot compiler. A nice GUI is included.
SmallEiffel : The GNU compiler for the Eiffel language. Requires an ANSI C compiler. Supports AIX, Amiga, BeOS, BSD, Cygwin, MSDOS, FreeBSD, GNU/Hurd, GNU/Linux, HP-UX, IRIX, MacOS, NetBSD, NeXT, OS/2, OSF1, QNX, SCO, Solaris, OpenVMS, Windows 95/98/NT/2K and XENIX.
Inno Pascal : Inno Pascal is a simple Pascal compiler for Win32. It produces compact, native-code x86 executables without requiring any external assemblers or linkers. It was written entirely from scratch; it is not based on any other existing compilers. Full source code is included under the GPL license.
Harbour Project : Harbour is an Open Source Clipper Compatible Compiler. It includes OO extentions, and lots of useful adds. The Licence is GNU+Harbour Exception, what means that the licence does not infects the programs you produce with the compiler.
