gcc 9.2.1 with -flto flag suspects some uninitialized variables which become
initialized in every code path where they are used. These false positives
are "fixed" by this patch in the most naïve way.
This allows to compile git with gcc 9, link-time optimization, and using the
DEVELOPER=1 switch (which sets -Werror).
