Argh, it is missing warning flags in Makefile:
+CFLAGS += $(WERROR_FLAGS)
When above added "make" also gives "unused variable" warnings.
Even we don't observe the issue with current makefile, if someone builds with:
'make EXTRA_CFLAGS="-Wunused-variable"' will observe the warnings.
That is why I am for backporting this patch, does it make sense?
And would you mind adding above CFLAGS update into this patch?
