So? Do we have a plan of filing a PR for each sorry message?

why does

struct foo x = {
    i: 0
};

work?

BTW, clang works fine:

[hjl@gnu-6 tmp]$ /opt/llvm.old/bin/clang -c i.c
i.c:6:5: warning: use of GNU old-style field designator extension
      [-Wgnu-designator]
    i: 0
    ^~
    .i = 
1 warning generated.

This works:

[hjl@gnu-6 tmp]$ cat i.cc
struct foo {
  char x[128];
  unsigned* i;
};
struct foo x = {
    "foo",
    .i = 0
};
[hjl@gnu-6 tmp]$ g++ -c i.cc
[hjl@gnu-6 tmp]$

I'm not saying that some work should not be done, I'm saying that sorry message
normally correspond to *known* issues, we don't need PRs for those, more or
less by definition. But what can I tell you, if you like to have a PR for this,
let's have it.

--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
C++20 added this support, G++ supports mixing styles by default but not out of
order. It was explicitly decided not support out of order.
So closing as fixed for GCC 8.
