32 bits here on Cygwin I guess and does not fit (1<<33)+140!) rather than
int64_t, whence the warnings during compilation.

but anywhere where long is only 32 bits.
That makes a lot of sense. It was a recent change, and I clearly have not
built & tested on my 32-bit laptop recently. (I will do in future, I
promise!). I take it that the solution is to redefine that variable as
int64_t?
