f17 doesn't include glibc 2.16, just patched glibc 2.15, which doesn't have
these header changes yet.
The thing I don't like on the last patch is that it hardcodes configure time
tests, so when glibc is upgraded say from 2.15 to 2.16, but gcc isn't upgraded,
suddenly anything that includes <cstdio> fails to compile.
So I'd prefer something like #c14 patch instead, perhaps testing a macro that
is
depending on __GLIBC_PREREQ defined in linux os-defines.h.

Can you please resolve this either way till tomorrow noon UTC (4.7
branching/4.7.0-rc1)?
Thanks.
