Well, I know nearly nothing about autoconf / automake, but isn't it
possible to have such a macro to be defined ONLY if it's not already
given by the environment?

#define rol(x, k) ((x << k) | (x >> (32 - k)))

It's a shame the C language doesn't provide a rotate operand, since
every known (to me at least) microprocessor architecture has
instructions for that.
