Sorry for the delay in the response ... :-(

Let me to clarify something about the Squid Windows support.

Currently Squid can be compiled in Windows using 3 different ways:

- Cygwin
- MSYS+MinGW
- MS Visual Studio (version 6 for Squid 2.6, version 2005 for Squid 3)

Cygwin and MSYS+MinGW are officially supported on the main
distribution of 2.6 and 3.0.
Both are a bash+gcc based build environment, so the build process is
identical to all other platforms. The MS Visual Studio build
environment is supported from the SQUID_NT_2_6 stable branch on
squid-cache.org and from the "nt" branches on Sourceforge.

There is an essential difference between Cygwin and MSYS+MinGW:
- Cygwin is based on a run-time emulation layer, so using Cygwin we
have a better source compatibility with worse performance and Windows
integration and to run, the executables need the cygwin run-time
called cygwin1.dll.
- MSYS+MinGW is based on a sort of "build-time emulation", so there
is a worse compatibility, but the performance are very good. At
run-time, the executables need only the standard Windows C Runtime
Library, msvcrt.dll, available on any Windows machine. MinGW doesn't
provide any kind of emulation layer.

So when speaking about Windows, the used operating system is
significative only at run-time, not at build-time.

Using MSYS+MinGW and MS Visual Studio, the Microsoft IPv6 support
must be enabled raising the target platform from standard win32 to
Windows XP/2003, but the resulting executable cannot run on previous
Windows versions.
For the IPv4 only build test, the win32 standard target must be used.

Regards

Guido
