portability of "designated initializers" - Mailing list pgsql-hackers

Hi,

I wonder how portable designated initializers are.  As far as I can tell
they were only defined in C99.  Can we use them in our source?  If not,
is there a way to do this in C89?

I mean something like this:

typedef struct foo {       char    type;       union {               int     ival;               float   fval;       }
val;
} foo;

static foo foos[2] = {       {                      .type = 'i',               .val.ival = 42       } , {
  .type = 'f',               .val.fval = 2.78       }
 
};
