Bug ID: 82644
Summary: Non-standard hypergeometric special functions defined
in strict modes
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
#define hyperg 1
#include <cmath>
In C++17 this fails to compile:
hyper.cc:1:16: error: expected unqualified-id before numeric constant
#define hyperg 1
^
hyperg is not a reserved name, so we shouldn't be defining it for -std=c++17,
only -std=gnu++17
