GCC 11 on Feodra 34 emits a false-positive warning like this:

This breaks the build with --enable-Werror. Initializing 'n' to
avoid the warning.

Hi Ilya,
I'm actually compiling now ovs on FC34 with --enable-Werror and I'm
not hitting a compilation issue.
Maybe there is something else related to the compilation issue?
gcc (GCC) 11.1.1 20210531 (Red Hat 11.1.1-3)
Thanks,
Roi
