for Windows target
This is runtime and headers from latest mingw32-2.0.0
package. Here is old port `devel/mingw-' from 1.0.0 package,
but maintainer of this old port syay, taht he don't want
update it, because new versions is not too stable. It is
good idea, to have old and stable environment (with old and
good-known gcc-2.95, etc) and new one. We have many versions
of native gcc in `lang/', for example.
