Updating from version 6 -> 8 from upstream. Declarations for variables
and function bodies were added to avoid unnecessary failures with
-Werror.
(cherry picked from commit 4cc91ceb3992ef4f51302b56178c3b2c2aeaaaad)
Appears that this file used to get included as a side effect of
gettext. After the change to gettext version requirements this file
no longer got copied to the package and so the build was broken.
