OK - it is supported, but "not in the same way as gcc".


Getting it to simplified cases:

No GO is stated as: flexible array member cannot be used as a member of 
a structure - line25

    +23  struct yyy {
    +24          char *newLBL;
    +25          http_auth_param_t auth[];
    +26  };
    +27
    +28  struct yyy
    +29  YYY[] = {
    +30     (struct yyy) {
    +31        .newLBL = "LBL1"
    +32     },
    +33     (struct yyy) {
    +34        .newLBL = "LBL2"
    +35     }
    +36  };
!cc c99_comp_literal.c;
"c99_comp_literal.c", line 29.1: 1506-995 (S) An aggregate containing a 
flexible array member cannot be used as a member of a structure or as an 
array element.

So, to get it to work with a pointer "inside" the data needs to be 
initialized more like this:
(what was line 25, is now line 32)

    +11          struct xxx {
    +12                  char *lbl;
    +13                  http_auth_param_t a[];
    +14          };
    +15          struct xxx X1 = (struct xxx) {
    +16                  .lbl = "labelX",
    +17                  .a = {
    +18                     (http_auth_param_t) { .p1 = "c1" },
    +19                     (http_auth_param_t) { .p2 = "g2" },
    +20                     (http_auth_param_t) { }
    +21                  }
    +22          };
    +23          struct xxx X2 = (struct xxx) {
    +24                  .lbl = "labelX",
    +25                  .a = {
    +26                     (http_auth_param_t) { .p1 = "z1" },
    +27                     (http_auth_param_t) { }
    +28                  }
    +29          };
    +30  struct yyy {
    +31          char *newLBL;
    +32          http_auth_param_t *auth;
    +33  };
    +34
    +35  struct yyy
    +36  YYY[] = {
    +37     (struct yyy) {
    +38        .newLBL = "LBL1",
    +39        .auth = X1.a
    +40     },
    +41     (struct yyy) {
    +42        .newLBL = "LBL2",
    +43        .auth = X2.a
    +44     },
    +45     { }
    +46  };

Shall work on a 'patch' asap (which might be in 24+ hours)
