Hi Sim,

Have you properly set up the paths of the WinARM? Moreover what OS are 
you using?

hello my friend I am really a novice in gcc compilation I just  replaced 
MCU by arm7 in makefile it seems to work but I receive another alert 
from the assembler who says name of missing cpu I reopened my makefile 
to find the line on which I must act j not found believing to act on 
-march and -mtune but on my makefile they do not appear
