Microsoft Visual C++/Intel C++ compiler support

Usage::

        $ waf configure --msvc_version="msvc 10.0,msvc 9.0" --msvc_target="x64"

or::

        def configure(conf):
                conf.env.MSVC_VERSIONS = ['msvc 10.0', 'msvc 9.0', 'msvc 8.0', 'msvc 7.1', 'msvc 7.0', 'msvc 6.0', 'wsdk 7.0', 'intel 11', 'PocketPC 9.0', 'Smartphone 8.0']
                conf.env.MSVC_TARGETS = ['x64']
                conf.load('msvc')

or::

        def configure(conf):
                conf.load('msvc', funs='no_autodetect')
                conf.check_lib_msvc('gdi32')
                conf.check_libs_msvc('kernel32 user32')
        def build(bld):
                tg = bld.program(source='main.c', target='app', use='KERNEL32 USER32 GDI32')

Platforms and targets will be tested in the order they appear;
the first good configuration will be used.

To force testing all the configurations that are not used, use the ``--no-msvc-lazy`` option
or set ``conf.env.MSVC_LAZY_AUTODETECT=False``.

Supported platforms: ia64, x64, x86, x86_amd64, x86_ia64, x86_arm, amd64_x86, amd64_arm

Compilers supported:

* msvc       => Visual Studio, versions 6.0 (VC 98, VC .NET 2002) to 12.0 (Visual Studio 2013)
* wsdk       => Windows SDK, versions 6.0, 6.1, 7.0, 7.1, 8.0
* icl        => Intel compiler, versions 9, 10, 11, 13
* winphone   => Visual Studio to target Windows Phone 8 native (version 8.0 for now)
* Smartphone => Compiler/SDK for Smartphone devices (armv4/v4i)
* PocketPC   => Compiler/SDK for PocketPC devices (armv4/v4i)

To use WAF in a VS2008 Make file project (see http://code.google.com/p/waf/issues/detail?id=894)
You may consider to set the environment variable "VS_UNICODE_OUTPUT" to nothing before calling waf.
So in your project settings use something like 'cmd.exe /C "set VS_UNICODE_OUTPUT=& set PYTHONUNBUFFERED=true & waf build"'.
cmd.exe  /C  "chcp 1252 & set PYTHONUNBUFFERED=true && set && waf  configure"
Setting PYTHONUNBUFFERED gives the unbuffered output.
