The options passed to internal binaries such as cc1 are not a documented public interface to GCC, so if you pass such options via -Wp you must expect to need to change your makefiles when the GCC-internal interfaces change. Instead, you should use the various public interfaces documented in cppopts.texi, which *are* stable interfaces. I think what you want here is "-MD -MF scripts/basic/.fixdep.d" with no -Wp. -- Joseph S. Myers jos...@codesourcery.com
