I looked at my original code and it is a bit different there. I placed it under rule_cc_o_c right after objtool command. If I remember correctly this is the correct recipe for .c->.o. Unfortunately I forgot the details and there is of course nothing about it in my notes. Does it help? Joao, is there a reason you moved it elsewhere? Miroslav
