Subject: PR c++/28407 * cp/decl.c (grokvardecl): Set
DECL_THIS_STATIC on file-scope const variables with implicit internal
linkage. * cp/tree.c (decl_linkage): Only return lk_external if it's
set.
PR c++/28409
* cp/decl2.c (constrain_visibility): Ignore the anonymous namespace
for extern C decls.
(VISIBILITY_STATIC): Rename to VISIBILITY_ANON.
Don't override explicit visibility.
* cp/decl2.c (constrain_visibility): Remove specified and reason
parameters. Don't touch decls that already have explicit visibility.
(determine_visibility): Do copy DECL_VISIBILITY_SPECIFIED from
template.
(determine_visibility_from_class): Reverse sense of
DECL_VISIBILITY_SPECIFIED test for target-specific visibility rules.
(constrain_class_visibility): Only complain about member visibility
if the member type is another class. Don't change visibility of the
current class.
* tree.c (remove_attribute): New fn.
* tree.h: Declare it.
