Microsoft .NET Framework Software Development Kit / Free Microsoft Visual
Unbelievably, the Microsoft Visual C/C++ command line compiler, along
with C#, VB.NET and JScript.NET, appears to be available from Microsoft
for download for free. The command line compiler is the same one that

not have an optimizer
- Open Source Watcom / OpenWatcom
The Watcom C/C++ compiler (now OpenWatcom C/C++ compiler) is now open
source and free. This compiler, which generates code for Win32, Windows
3.1 (Win16), OS/2, Netware NLM, MSDOS (16 bit and 32 bit protected mode),
etc, was a highly coveted compiler some years back (until Sybase terminated
- Mingw32 C & C++ Compilers
This system comes with the GNU C/C++ compiler, which you can use to
generate Win32 executables. It has its own <windows.h> which is
in the public domain. Applications generated using this system are supposed
to be faster than those generated by the Cygwin32 system (see elsewhere
on this page), and they are free from the encumberances of the GNU license.
- Digital Mars C/C++ Compiler
(Symantec C++ Replacement) :
Digital Mars C/C++ is a drop-in replacement for the Symantec C++ compiler,

dialect" of C. It enforces type safety, has a variety of checks
to protect against buffer overflows, array-bound violations, etc.
Leonardo IDE is a Macintosh-based IDE, compiler and debugger for C programs.
The Windows and Linux ports are said to be under development. The IDE
is useful for checking and debugging your source code, search for memory
- Bloodshed Dev-C++ C++
This is a Win32 integrated development environment that includes the
egcs C++ compiler and GNU debugger from the Mingw32 environment together
with an editor and other facilities to make program development using
the Mingw32 gcc compiler easier on a Windows platform. It also includes
