It should be -- I haven't done anything which really ought to affect it.
The code in signal.c and signal32.c seems to have a lot of duplication,
but also a lot of code which is _almost_ duplicated but just slightly
different for no adequately defined reason. I wonder if it makes sense
to have a go at unifying it a bit, or at least making the 32 and 64 bits
look alike if they _do_ have to be separate?
