This patch, relative to a tree with
<https://sourceware.org/ml/libc-alpha/2014-11/msg00736.html> (pending
review) applied, uses diagnostic control pragmas to disable warnings
in stdio-common/tst-printfsz.c for use of the deprecated
register_printf_function. Because this test is testing printf_size
and printf_size_info, and the latter has the interface expected for
register_printf_function instead of the newer
register_printf_specifier, it seems correct for this test to use the
deprecated interface (wrapping printf_size_info in some way to use
register_printf_specifier would seem an excessive change to what's
tested).
Tested for x86_64.

* stdio-common/tst-printfsz.c: Include <libc-internal.h>.
(main): Disable -Wdeprecated-declarations around calls to
register_printf_function.
