Thanks for noticing this and looking into it, @gsnw!

How about using the INT64_C(…) macro to specify the type of the constant instead of using a cast to int64_t?

On the affected macOS system, the type suffix for the numeric constant would need to be LL to avoid the warning, but on an x86_64 GNU/Linux system the type suffix should be L. The INT64_C(…) macro is intended to choose the correct suffix for the given system.

The following patch works on my x86_64 GNU/Linux system:

Ah thanks, I've learned something again. I didn't know that yet. I've changed it and tested it.
