I got caught up with computing Pi. Chudnovsky-Pi lives here on Github. It runs well on Cygwin and Unix, of course ;-). Strawberry Perl 64-bit is not built with true 64-bit integer support, unfortunately. Anyway, the Chudnovsky-Pi demonstration runs with Linux Bash Shell on Windows 10. The m4 binary is needed and optionally yasm, needed for MPIR. Hence, sudo apt-get install m4 yasm.
