This avoids pedantic warnings in C++98 caused by %zu in the format
strings passed to the __throw_out_of_range_fmt function:
include/bitset:845: warning: ISO C++98 does not support the 'z' gnu_printf
length modifier [-Wformat=]
The definition of the function is in src/c++11/functexcept.cc and
compiled using -std=gnu++11 so the %zu format works fine. We just can't
tell C++98 translation units that it works, so suppress the attribute in
C++98.
libstdc++-v3/ChangeLog:
* include/bits/stdexcept_throwfwd.h (__throw_out_of_range_fmt):
Do not use __format__ attribute for C++98.
