Bug ID: 124591
Summary: has_c_language_linkage does not recognize C language
linkage on function types
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: luigighiron at gmail dot com
Target Milestone: ---
The following program is incorrectly rejected by GCC:
#include<meta>
extern"C" using F=int();
static_assert(has_c_language_linkage(dealias(^^F)));
int main(){}
F is a function type with C language linkage, so has_c_language_linkage should
return true for dealias(^^F).
