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

Usage::

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

or::

	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.
Supported platforms: ia64, x64, x86, x86_amd64, x86_ia64

Compilers supported:

* msvc       => Visual Studio, versions 7.1 (2003), 8,0 (2005), 9.0 (2008)
* wsdk       => Windows SDK, versions 6.0, 6.1, 7.0
* icl        => Intel compiler, versions 9,10,11
* Smartphone => Compiler/SDK for Smartphone devices (armv4/v4i)
* PocketPC   => Compiler/SDK for PocketPC devices (armv4/v4i)
