That's not my experience in the first place: when I tried to get it
working on Solaris 11, I failed so completely that I decided to instead
follow the route already trodden by the Solaris/x86 file.

I doubt I'll have the time: there's quite a lot on my plate before 4.7.0
and I don't have that much time left for gcc issues these days.
Again: what's the justification for changing this code so late in the
game when it has been like this since 4.6.0 with no issues? I don't buy
it that support for s10_72 (a 7-year old Solaris 10 Beta) is enough to
break Solaris 11 (the current shipping release).
