I see it is also in version 11 - so, maybe still syntax:

This is the doc:

The following example passes a constant structure variable of type point 
containing two integer members to the function drawline:

drawline((struct point){6,7});

While the code is:
.challenges = (struct http_auth_challenge_test []) {
                         { .scheme = "Basic",
                                 .data = NULL,
                                 .params = (struct http_auth_param []) {
                                         { "realm", "WallyWorld" }, { NULL, NULL }
                                 }
                         },{
                                 .scheme = NULL
                         }

The difference I notice is that, much prettier btw, you are also specifying the struct .names, and perhaps, in
Compound literal syntax

"initializer_list" is exclusive of (additional) declarers.

The messages seem to indicate the parser does not like them being there...

To understand|study it, I simplified it to:

  +7  #include "http-auth.h"
     +8
     +9  struct http_auth_challenge_test {
    +10          const char *scheme;
    +11          const char *data;
    +12          struct http_auth_param *params;
    +13  };
    +14
    +15  struct http_auth_challenges_test {
    +16          const char *challenges_in;
    +17          struct http_auth_challenge_test *challenges;
    +18  };
    +19
    +20  /* Valid auth challenges tests */
    +21  static struct http_auth_challenges_test
    +22          valid_auth_challenges_tests[] = {
    +23                  { "Basic realm=\"WallyWorld\"",
    +24                          "Basic",
    +25                          NULL,
    +26                           "realm", "WallyWorld",
    +27                           NULL, NULL
    +28                  },{
    +29                          NULL,
    +30                          NULL,
    +31                          NULL, NULL
    +32                  }
    +33          };

(lots of experimenting!)
I got it down to these messages:

As 'it' kept complaining about the unnecessary opening { I am thinking that their design does not leave space fot nesting arrarys of initialization. And I would tend to agree with there being 'lazy'.
That does not fix my problem. Going to look for a - maybe less elegant - but workable (and if found I hope acceptable) work-around.
