Problem building g++ 4.1.1 on Cygwin

[Dave Yost <Dave at Yost dot com>]

I'm trying to build a 4.1.1 on cygwin that will let me use the 
-mno-cygwin argument.  I looked and looked on the web for the runes 
and finally heard somewhere in a dark alley that I should try 
something like the below.  I first ran Cygwin setup, and everything 
is up to date.

Any help would be greatly appreciated!

Thanks
