Hide internal printf functions [BZ #18822/21986]
Hide internal printf functions to allow direct access within libc.so and libc.a without using GOT nor PLT. Since __guess_grouping has been changed to take 2 arguments by commit a1d84548c8aa7023cd039c85f81b831eef6d4a4c Author: Ulrich Drepper <drepper@redhat.com> Date: Fri Feb 11 18:50:36 2000 +0000 the third argument passed to __guess_grouping is removed. [BZ #18822] [BZ #21986] * include/printf.h (__printf_fphex): Add attribute_hidden. (__guess_grouping): New prototype. * stdio-common/printf_fp.c (__guess_grouping): Removed. * stdio-common/reg-printf.c (__register_printf_specifier): Add libc_hidden_proto and libc_hidden_def. * stdlib/strfmon_l.c (__guess_grouping): Removed. (__vstrfmon_l): Remove the third argument passed to __guess_grouping.
