Bug ID: 57640
Summary: Explicit call of system literal operator complains
about leading underscore.
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: 3dw4rd at verizon dot net
Since we added literal operators to the standard library I noticed that
if you explicitly call a std literal operator
-----------------------------------------------------------
#include <chrono>
using namespace std::literals::chrono_literals;
auto blooper = operator"" min(45.0L);
-----------------------------------------------------------
you get
-----------------------------------------------------------
blooper.cc:5:27: warning: literal operator suffixes not preceded by ‘_’ are
reserved for future standardization [enabled by default]
auto blooper = operator"" min(45.0L);
-----------------------------------------------------------
The definition in the system header doesn't trigger this but the explicit call
in user code does.
Mot fatal, and won't be commonly hit butI'd like to fix it.
