I'm fine with the change, but going forward please be more specific
with your descriptions: Whether or not warnings get emitted for a
certain piece of code often highly depends on compiler version. Let
us know which version you've run this into with. For the record, I'm
building on a wide range of gcc versions every once in a while, and
I've not come across this warning so far (or else I would have sent
a patch). The really old versions (4.1.x for example) can't really be
used anymore for certain other reasons anyway, and I think it's
about time we at least raise the bar a little (also for binutils, which
iirc was the actual problem with here, using a version matching in
original release time with gcc 4.1.x).
gcc version 4.1.2 20080704 (Red Hat 4.1.2-55)
Thanks
Zhenzhong
