[Bug c++/13590] [DR39] Non-existing ambiguity when inhering through virtuals two identical using declarations.

[gcc-bugzilla at kayari dot org]

------- Comment #19 from gcc-bugzilla at kayari dot org  2005-12-10 13:17 -------
would the summary be clarified by changing "Non-existing ambiguity when
inhering through virtuals two identical using declarations" to "Ambiguity due
to two using declarations for same member of virtual base" ?
