I've checked in this patch which fixes another long-standing
documentation issue in bugzilla. Here there was a missing entry for
__attribute__((visibility ("protected"))) (or whatever) in the section
on variable attributes, although there was an example showing its use on
a variable in the function attributes section. I also did confirm that
the attribute does work on variables.
