Bug ID: 107128
Summary: armhf: floatn-common.h:214:9: error: multiple types in
one declaration
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: malat at debian dot org
Target Milestone: ---
Steps:
% cat p.cxx
#include <stdio.h>
int main() { return 0; }
Lead to:
% /usr/lib/gcc-snapshot/bin/g++ -v p.cxx
