[C++ Patch] PR 65811

[Paolo Carlini <paolo dot carlini at oracle dot com>]

Hi,

the testcase shows that after Jason's r222134 in some cases it can still 
happen that TREE_PUBLIC is false and DECL_COMDAT is true, thus the 
assertion in vague_linkage_p triggers. For the testcase, in 
duplicate_decls, newdecl starts with both flags true and only the former 
becomes false when its value is copied from olddecl. Alternately to the 
simple tweak which I tested succesfully, I briefly wondered if we 
shouldn't just copy DECL_COMDAT too, in duplicate_decls, but that also 
causes the regression of ext/gnu-inline-global.C and 
ext/gnu-inline-namespace.C.

Thanks,
Paolo.
