Chrome’s JS engine (V8, shared with Node.js) does it both ways, depending on
context:

-0

Says “0”
Two different versions of Perl (5.16.3 on CentOS 7 and 5.18.4 on macOS 10.14.5)
prints “0” via all three paths I’ve tried: print(), say(), and Data::Dumper.
Clang on macOS agrees with your glibc result, for both printf() and cout.
