Please add gnu arm assembler scheme for pn. And can everybody add  this 
for notepad++. Im using your toolchain in university and want to make it 
better. Can you add me to your group?

I think you have posted to the wrong forum. While these tools are 
packaged with WinARM, and perhaps other GNU ARM packages, they are not 
developed by these projects.
