Designated initializer warning using compound literal

Compiling with `-std=c99 -Wextra` and using a compound literal to initialize a
member in a designated initializer:

struct T { int a; int *b; int c; }; 

struct T t = {.b = (int[]){1}};

Raises a warning 

missing initializer for field ‘c’ of ‘struct T’
[-Werror=missing-field-initializers]

This happens when the initialized member is not the last member of the struct.
