-/* A hash table of fixed size.  Multiple threads can access it read-only

-   at the same time.
-   This hash table has global scope, so that when an application uses both
-   GNU libintl and gnulib, the application sees only one hash table.  (When
-   linking statically with libintl, the fact that localename-table.c is a
-   separate compilation unit resolves the duplicate symbol conflict.  When
-   linking with libintl as a shared library, we rely on ELF and the symbol
-   conflict resolution implemented in the ELF dynamic loader here.)
-   Both the libintl overrides and the gnulib overrides of the functions
-   newlocale, duplocale, freelocale see the same hash table (and the same lock).
-   For this reason, the internal layout of the hash table and the hash function
-   MUST NEVER CHANGE.  If you need to change the internal layout or the hash
-   function, introduce versioning by appending a version suffix to the symbols
-   at the linker level.  */
