That sounds reasonable to me. I've pushed a patch that implements this, I think.

I've flipped it round so that the `#define` is used for a 32-bit time_t. That way the common case (and hopefully more common as we approach Y2038) is the default one, without needing an extra command-line option.

And I've centralised the cmake code that decides on the size of time_t, so that the same variable is used to control both the command-line `#define` and the choice of output `time_t.h`.
