Provide cmd file for building both 32-bit and 64-bit libraries on Windows with Microsoft Visual C++

[rassokhin@…]

It would make sense to provide a cmd file to automate bootstrapping and building both 32-bit and 64-bit libraries (in the Debug and Release configurations) on Windows (placing them under stage32 and stage64, respectively). Running bootstrap and b2 with no command-line arguments as recommended in the Getting Started guide will build only 32-bit libraries. In order to build 64-bit libraries, one has to consult bjam docs to figure out which parameters/options to use. Since targeting both 32-bit, and 64-bit architectures is quite common for developers working under Windows, having a batch file to automate Boost library builds for both architectures in one go will save them some time and effort.

Agreed! I've been trying to build 1_55 in 64-bit mode and no matter what combination of address-model=64 or arichetecture=x86 I can't get it to work.

This build command doesn't seem to work:

b2 -j 8 -q ^
	--without-mpi ^
	--build-dir=tmp_bld_dir ^
	--variant=release ^
	--build-type=minimal ^
	architecture=x86 ^
	adress-model=64 ^
	toolset=msvc ^
	link=shared ^
	runtime-link=shared ^
	threading=multi ^
	install

Oh yeah, it would be nice if the b2 reported it was building in 64-bit mode.
