During the conversion to support 64 bit time on some architectures with __WORDSIZE == 32 && __TIMESIZE != 64 the libc_hidden_def attribute for eligible functions was by mistake omitted. This patch fixes this issue and exports (and allows using) those functions when Y2038 support is enabled in glibc.
