 * Note: It's important that none of these affects 'zstd.h' (only the
 * implementation files we're amalgamating).
 *
 * Note: MEM_MODULE stops xxhash redefining BYTE, U16, etc., which are also
 * defined in mem.h (breaking C99 compatibility).
 *
 * Note: the undefs for xxHash allow Zstd's implementation to coincide with
 * standalone xxHash usage (with global defines).
 *
 * Note: if you enable ZSTD_LEGACY_SUPPORT the combine.py script will need
 * re-running without the "-x legacy/zstd_legacy.h" option (it excludes the
 * legacy support at the source level).
