Suggested change to nt\configure.bat

[Lennart Borgman]

Below are some small changes to nt\configure.bat that I think would make it
more helpful. It checks for more programs that are actually needed during
the build and tells how to get them. It also checks to see if bootstrap is
necessary and tell more in detail how to do the build.

What do you think of such a change? Could this be accepted?

diff to make it useful here?)
