There was a suggestion to support 64-bit rotates as well.  That would
use uint64_t.  Does stdint.m4 define some symbol that may be useful
here?  The code is rather complex so I'm trying to save time asking here
first.  I guess stdint.h cannot always define a uint64_t type, for
example if the platform does not support it?

Alternatively, bitrotate.m4 could check for uint64_t and enable rotl64
and rotr64 functions only if the type exists.  That may be cleaner
