[Bug c/44316] New: "initialization from incompatible pointer type" struct initilization error handling

[herron dot philip at googlemail dot com]

This test case demonstrates what i mean:

struct my_struct {
  int x;
  int (*hook_a)( void );
};

int func_a( void )
{
  return 1;
}

void func_b( void )
{
  func_a( );
}

int main( void )
{
  struct my_struct a = { 1, &func_a };
  struct my_struct b = { 2, &func_b };

  return 0;
}

When initializing a struct it would be nice to have an error message detailing
the field which has the incompatible pointer type.

Here is what gcc trunk says:

opsy. gcc --syntax-only pr.c
pr.c: In function ‘main’:
pr.c:20:10: warning: initialization from incompatible pointer type [enabled by
default]

The particular case motivating this PR was getting a declaration wrong
and then getting an error from LANG_HOOKS_INITIALIZER.  In this case the
location info is not helpful.

You could probably make WARN_FOR_ASSIGNMENT use pedwarn_init.
