Bug ID: 59295
Summary: useless warning: 'Bar' is already a friend of 'Foo'
[enabled by default]
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ppluzhnikov at google dot com
Google ref: b/11542609
Using trunk gcc:
g++ (GCC) 4.9.0 20131125 (experimental)
/// -- cut ---
class Foo {
friend class Bar;
friend class Bar;
};
/// -- cut ---
g++ -c t.cc
t.cc:3:15: warning: 'Bar' is already a friend of 'Foo' [enabled by default]
friend class Bar;
^
This warning is purely stylistic -- no possible bug could happen when this
warning is disabled.
It is also not suppressable :-(
In actual code, both friend declarations come from macro expansion, and are
somewhat hard to get rid of.
