    Avoid more -Wformat-diag warnings [PR103758]
    
    Let's use "%<x>, %<y>, or %<z>" rather than "[x|y|z]" as in the rest of
    our codebase.
    
            PR c++/103758
    
    gcc/c-family/ChangeLog:
    
            * c-pragma.c (handle_pragma_scalar_storage_order): Use %< %> in
            diagnostic messages.
            (handle_pragma_diagnostic): Likewise.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/sso-6.c: Update dg-warning.
