Subject: y2038: fix: Add missing libc_hidden_def attribute for some syscall wrappers
X-Git-Tag: glibc-2.32~491
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=03343699496edd866141a8bbdfeb19ae98537394;p=thirdparty%2Fglibc.git

y2038: fix: Add missing libc_hidden_def attribute for some syscall wrappers

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.
