As you notice, you get libraries created with cygwin naming. This
is because you build b2 using cygwin gcc, so it assumes you
are building for cygwin thereafter. You should be able to use

	target-os=windows

to improve on this

You already have it, see libboost_system-vc100-mt-1_47.a. I think that target-os=windows
will also fix the extension.

See above.

See http://www.boost.org/doc/libs/1_47_0/more/getting_started/windows.html#library-naming again,
the third column of the table in particular.
