What's the point of having a policy of turning gcc's warnings to painful
levels when it appears that commit policy will accept new code that increases
the number of compiler warnings?
eg, why is there need to patch this?

end RANT. Awkward question:
interpreter.c:69: warning: cast increases required alignment of target type
If we're serious about -Wcast-align we MUST change the generic pointer from
void * (which will have the most loose cast alignment) to something that
has the highest alignment on the given machine. (typically double *, I'd
assume).
All the world is not a VAX^Wx86, and on some platforms we're compiling on
even int * must be aligned, let alone things like long double * or complex
structs.
If we're not serious about doing this, please could we drop -Wcast-align
