I have a number of very long arrays. No run-time sort is possible. It is also time consuming to sort them manually. Moreover, new elements can be added in any order later, so I would like to sort them by value using C preprocessor or maybe there is any compilers flag (GCC)?

For example:

sometype S[] = {
  {somevals, "BOB", someothervals},
  {somevals, "ALICE", someothervals},
  {somevals, "TIM", someothervals},
}

must be sorted so:

sometype S[] = {
   {somevals, "ALICE", someothervals},
   {somevals, "BOB", someothervals},
   {somevals, "TIM", someothervals},
}
