/* Return a symbol (a canonical representation) for <cstr>. An advantage of
symbols is that they can be compared for equality by a simple pointer
comparison, rather than using <strcmp()> (as it is done in <gt_strcmp()>).
Furthermore, a symbol is stored only once in memory for equal <cstr>s, but
keep in mind that this memory can never be freed safely during the lifetime
of the calling program. Therefore, it should only be used for a small set of
<cstr>s. */
