--- Comment #3 from freezer at posteo dot de ---
In my opinion the current behavior is somehow inconsistent since the carets are
displayed for included files.
Example:
// test.cpp
#include <coroutine>
int main(int argc, char **argv)
{
return 0;
}
$ cat test.cpp | g++ -Wall -Wextra -xc++ -
In file included from <stdin>:1:
/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/include/g++-v10/coroutine:295:2: error:
#error "the coroutine header requires -fcoroutines"
295 | #error "the coroutine header requires -fcoroutines"
| ^~~~~
<stdin>: In function ‘int main(int, char**)’:
<stdin>:3:14: warning: unused parameter ‘argc’ [-Wunused-parameter]
<stdin>:3:27: warning: unused parameter ‘argv’ [-Wunused-parameter]
