[m4/ChangeLog]
* sha512.m4 (gl_SHA512): Add u64.h to AC_LIBSOURCES. [lib/ChangeLog] Port sha512sum to hosts where uintmax_t is only 32 bits, e.g., HP/Tandom NonStop OSS circa 2005 has 32-bit uintmax_t, 64-bit intmax_t. * u64.h: New file. * sha512.c (SWAP, sha512_init_ctx, sha384_init_ctx, sha512_read_ctx): (sha384_read_ctx, sha512_conclude_ctx, sha512_process_bytes): (sha512_round_constants, F2, F1, sha512_process_block): (S0, S1, SS0, SS1, M, R): Rewrite to use u64.h instead of assuming uint64_t. * sha512.h: Include u64.h rather than stdint.h. (rol64): Remove; moved to u64.h and renamed to u64rol.
