OK, great.

Sorry about that, I did not realize I was working with a hacked copy of 
the source. 

I have now downloaded the original ngaro.c, but it is using the termios stuff
that mingw does not understand. When removing that it works in 32-bit mode
but still no luck in 64-bit mode. (I guess there is a problem with int etc.)

Try looking for 'retro' using Google :-) 
The best entry seems to be through the retro blog.

It proved far easier to download the gForth vm for retro and port it to iForth64.
Even without the messy literal ` immediate stuff it runs fine. I added
the missing getEnv and cw ch underpinning and 'fixed' the output of ^J and 
the input of '\' on Windows.

The result for the 'fib' benchmark puzzles me.
