Bug ID: 101168
Summary: gnu++14 complains about altivec types defined with
using keyword in the same file with preprocessor
macros
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tuliom at ascii dot art.br
Target Milestone: ---
Step to reproduce the error:
$ cat issue.cc
#include <altivec.h>
using vdbl = __vector double;
#define BREAK 1
$ g++ -std=gnu++14 -c issue.cc
issue.cc:4:15: error: expected type-specifier before numeric constant
4 | #define BREAK 1
| ^
issue.cc:4:9: note: in expansion of macro ‘BREAK’
4 | #define BREAK 1
| ^~~~~
The error does not reproduce when using -std=c++14.

Like the case in PR101168: using vdbl = __vector double; #define BREAK 1 For this case, "vector double" is followed by CPP_SEMICOLON and then EOF. There is no more tokens need to check for this case.
