Could g++ suggest header for SIGABRT?

<csignal> just includes <signal.h> I saw in the file. But anyway, I was
compiling as 

#1 with x86-64 gcc (trunk)
<source>: In function 'int main()':

<source>:6:18: error: 'SIGABRT' was not declared in this scope

    6 |     std::cout << SIGABRT;

      |                  ^~~~~~~

Compiler returned: 1


//#include <csignal>
#include <iostream>

int main()
{
    std::cout << SIGABRT;
}



and C version

//#include <signal.h>

int main()
{
    return SIGABRT;
}



#1 with x86-64 gcc 8.3
<source>: In function 'main':

<source>:5:12: error: 'SIGABRT' undeclared (first use in this function)

     return SIGABRT;

            ^~~~~~~

<source>:5:12: note: each undeclared identifier is reported only once for each
function it appears in

Compiler returned: 1=
