One typical way is to find a header that is used everywhere and add:

    #ifndef __GCC__
    #define __attribute__()
    #endif

I don't think we have a header like this other than config.h.
Adding non-configure-generated defines there is mildly frowned upon
but can be done.

FWIW, one nice thing about adding defines instead of using plain
__attribute__ everywhere is that you can make the attributes
conditional on gcc version.  This doesn't seem to have affected us yet
though.
