We maintain those cheat-sheets in nt/INSTALL.

A few comments regarding the list of packages:

I don't think MinGW packages for Autoconf and Automake are needed, or
even useful.  You need MSYS packages instead, installed into the MSYS
tree.  You can find such packages on the ezwinports site (they are
also easy to build and install by yourself.)

> gdb-7.6.1-1-mingw32-bin.tar.lzma

There's a much newer (and much more functional) port of GDB 7.10 on
ezwinports.

> make-3.82.90-2-mingw32-cvs-20120902-bin.tar.lzma

Make 4.1 is available from ezwinports.  The above is not even an
official release.
