Well, actually I'm not using Sparse for my project. I want to use the
'designated_init' attribute since it is supported by GCC. And I want to use the
attribute mainly so that users of my library get the warning, and I can't
control what flags the user uses (and GCC doesn't have a
-Wno-universal-initializer flag anyway).

That's fine, but perhaps GCC should add something like
-Wno-universal-initializer and use it by default. I'll suggest that in the GCC
bug (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95379).
