Can you compile from the cmd window?  If you cannot, then your MinGW
installation is broken, and this is not an Emacs problem.  You need to
fix that first.

If you can compile from the cmd window, but not from Emacs, then your
PATH and the list of directories where Emacs looks for programs are
different.  To make them identical, do NOT change PATH from the cmd
window, but instead from the Computer Properties, in the Advanced
section.
