[Bug pch/45441] New: PCH: invalid file in error messages

["gavv dot ml at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hello.

$ cat 1.h
void f();

$ cat 2.h
# include "1.h"

$ cat 1.c
#include "2.h"

int main()
{
  a = b;
}

$ gcc 1.c 
1.c: In function 'int main()':
1.c:5: error: 'a' was not declared in this scope
1.c:5: error: 'b' was not declared in this scope

But:

$ g++ 1.h 
$ ls
1.c  1.h  1.h.gch  2.h
$ gcc 1.c
2.h: In function 'int main()':
2.h:5: error: 'a' was not declared in this scope
2.h:5: error: 'b' was not declared in this scope

Now error is located in "2.h" instead of "1.c". If "1.c" includes "1.h"
directly (not through "2.h") everything is ok.
