Bug #: 57183
Summary: [C++11]auto and -Wunused-variable
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: frankhb1989@gmail.com
Case:
constexpr float PI_0 = 3.1415926F;
constexpr auto PI_1 = 3.1415926F;
const float PI_2 = 3.1415926F;
const auto PI_3 = 3.1415926F;
int main(){}
Using gcc version 4.8.0 (rev2, Built by MinGW-builds project).
g++ a.cc -std=c++11 -Wall
a.cc:2:16: warning: 'PI_1' defined but not used [-Wunused-variable]
constexpr auto PI_1 = 3.1415926F;
^
a.cc:4:12: warning: 'PI_3' defined but not used [-Wunused-variable]
const auto PI_3 = 3.1415926F;
^
The difference between auto and non-auto declarations seems to be not intended.

PI_1 and PI_3 are "d" instead of "r"
