-/* Each TMP_ALLOC uses __gmp_allocate_func to get a block of memory of the
-   size requested, plus a header at the start which is used to hold the
-   blocks on a linked list in the marker variable, ready for TMP_FREE to
-   release.
-
-   Callers should try to do multiple allocs with one call, in the style of
-   TMP_ALLOC_LIMBS_2 if it's easy to arrange, since that will keep down the
-   number of separate malloc calls.
-
-   Enhancements:
-
-   Could inline both TMP_ALLOC and TMP_FREE, though TMP_ALLOC would need the
-   compiler to have "inline" since it returns a value.  The calls to malloc
-   will be slow though, so it hardly seems worth worrying about one extra
-   level of function call.  */
