Starting with AIX6.1 there is support in libc.a for uuid (RFC4122) This patch provides the changes needed for this integration with the OS. On AIX the base function is uuid_create() rather than uuid_generate_time() The AIX uuid_t typedef is more aligned to the UUID field based definition while the Linux typedef that is more aligned with UUID bytes (or perhaps UUID bytes_le) definitions.
