Currently, castring away volatile from a pointer makes -Wcast-qual
claim that __attribute__((noreturn)) was cast away (see bugzilla
55383). The attached patch, originally written by Manuel López-Ibáñez
and updated to match trunk by me, correctes that. No regressions on
gcc from applying this patch (as reported by "make check") were seen.
