__attribute__(()) wasn't added by the patch ;)
You can write a macro to effectively remove this directive when using
an alternate compiler. There is some info in the gcc help on this, but
this does the trick:
#define __attribute__()
There would be a bit more work required to use an alternate compiler,
but this only makes sense to me if you are using a processor not
supported by gcc.
