Big deal. It is your useless 'typedef' that is the problem:

  /* mha: The original typedef was comletely senseless. It provided no
     new type name. An analogous typedef would be 'typedef int;'. I
     have remove the useless keyword 'typedef', since the attempted use
     doesn't need it. */

struct SomeStruct_t
{
     int Member1;
     int Member2;
     int Member3;
};

  /* mha: The original return type for main was 'void'. This is
     illegal, illiterate, and proves that the original poster has
     violated civilized norms by neither following the newsgroup nor
     checking the FAQ before posting. Fixed. */

int main(void)
{
     struct SomeStruct_t ExampleStructure;
     ExampleStructure.Member1 = 1;
     return 0; /* mha: for C89 or C90 */
}
