So now the new mystery is: why does it take you a whopping 7.5 min to
compile the C sources of Emacs? It takes about 30 sec for me with GCC
3.4.x; GCC 4.7.2 that you use should be about 2 times slower, so I'd
expect something like 1 min, not 7.5.
Try this:
cd nt
touch ../src/config.h
make -j6
and time the last command.

You should be able to do better, like 8min at most. Something is
still getting in your way.

Maybe that's your problem. Does the time go down if you repeat that
command? If it doesn't, you may wish to try from cmd.exe.
